intel UG-01173 Fault Injection FPGA IP Core

Fault Injection Intel® FPGA IP Core User Guide

The Fault Injection Intel® FPGA IP core injects errors into the configuration RAM (CRAM) of an FPGA device. This procedure simulates soft errors that can occur during normal operation due to single event upsets (SEUs). SEUs are rare events and are therefore difficult to test. After you instantiate the Fault Injection IP core into your design and configure your device, you can use the Intel Quartus® Prime Fault Injection Debugger tool to induce intentional errors in the FPGA to test the system’s response to these errors.

Features

• Allows you to evaluate system response for mitigating single event functional interrupts (SEFI).
• Allows you to perform SEFI characterization in-house, eliminating the need for entire system beam testing. Instead, you can limit the beam testing to failures in time (FIT)/Mb measurement at the device level.
• Scale FIT rates according to the SEFI characterization that is relevant to your design architecture. You can randomly distribute fault injections throughout the entire device, or constrain them to specific functional areas to speed up testing.
• Optimize your design to reduce disruption caused by a single event upsets (SEU).

Device Support

The Fault Injection IP core supports Intel Arria® 10, Intel Cyclone® 10 GX and Stratix® V family devices. The Cyclone V family supports Fault Injection on devices with the -SC suffix in the ordering code. Contact your local sales representative for ordering information on -SC suffix Cyclone V devices.

Fault Injection IP Core FPGA Performance and Resource Utilization

The Intel Quartus Prime software installation includes the Intel FPGA IP library. This library provides many useful IP cores for your production use without the need for an additional license. Some Intel FPGA IP cores require purchase of a separate license for production use. The Intel FPGA IP Evaluation Mode allows you to evaluate these licensed Intel FPGA IP cores in simulation and hardware, before deciding to purchase a full production IP core license. You only need to purchase a full production license for licensed Intel IP cores after you complete hardware testing and are ready to use the IP in production. The Intel Quartus Prime software installs IP cores in the following locations by default:

Note: The Intel Quartus Prime software does not support spaces in the installation path.

Customizing and Generating IP Cores
You can customize IP cores to support a wide variety of applications. The Intel Quartus Prime IP Catalog and parameter editor allow you to quickly select and configure IP core ports, features, and output files.

IP Catalog and Parameter Editor
The IP Catalog displays the IP cores available for your project, including Intel FPGA IP and other IP that you add to the IP Catalog search path.. Use the following features of the IP Catalog to locate and customize an IP core:

• Filter IP Catalog to Show IP for active device family or Show IP for all device families. If you have no project open, select the Device Family in IP Catalog.
• Type in the Search field to locate any full or partial IP core name in IP Catalog.
• Right-click an IP core name in IP Catalog to display details about supported devices, to open the IP core’s installation folder, and for links to IP documentation.
• Click Search for Partner IP to access partner IP information on the web.

The parameter editor prompts you to specify an IP variation name, optional ports, and output file generation options. The parameter editor generates a top-level Intel Quartus Prime IP file (.ip) for an IP variation in Intel Quartus Prime Pro Edition projects. The parameter editor generates a top-level Quartus IP file (.qip) for an IP variation in Intel Quartus Prime Standard Edition projects. These files represent the IP variation in the project, and store parameterization information.

Functional Description
With the Fault Injection IP core, designers can perform SEFI characterization in-house, scale FIT rates according to SEFI characterization, and optimize designs to reduce effect of SEUs.

Single Event Upset Mitigation

Integrated circuits and programmable logic devices such as FPGAs are susceptible to SEUs. SEUs are random, nondestructive events, caused by two major sources: alpha particles and neutrons from cosmic rays. Radiation can cause either the logic register, embedded memory bit, or a configuration RAM (CRAM) bit to flip its state, thus leading to unexpected device operation. Intel Arria 10, Intel Cyclone 10 GX, Arria V, Cyclone V, Stratix V and newer devices have the following CRAM capabilities:

• Error Detection Cyclical Redundance Checking (EDCRC)
• Automatic correction of an upset CRAM (scrubbing)
• Ability to create an upset CRAM condition (fault injection)

For more information about SEU mitigation in Intel FPGA devices, refer to the SEU Mitigation chapter in the respective device handbook.

Fault Injection IP Pin Description

The Fault Injection IP core includes the following I/O pins.

Fault Injection IP Core I/O Pins

(EMR Unloader IP). This signal is asserted when a CRC error has been detected by the device’s EDCRC.
emr_data| input| Error Message Register (EMR) contents. Refer to the appropriate device handbook for the EMR fields.

This input complies with the Avalon Streaming data interface signal.

emr_valid| input| Indicates the emr_data inputs contain valid data. This is an Avalon Streaming valid interface signal.
Reset| input| Module reset input. The reset is fully controlled by the Fault Injection Debugger.
error_injected| output| Indicates an error was injected into CRAM as commanded via the JTAG interface. The length of time this signal asserts depends on your settings of the JTAG TCK and control block signals. Typically, the time is around 20 clock cycles of the TCK signal.
error_scrubbed| output| Indicates the device scrubbing is complete as commanded via the JTAG interface. The length of time this signal asserts depends on your settings of the JTAG TCK and control block signals. Typically, the time is around 20 clock cycles of the TCK signal.

Using the Fault Injection Debugger and Fault Injection IP Core

The Fault Injection Debugger works together with the Fault Injection IP core. First, you instantiate the IP core in your design, compile, and download the resulting configuration file into your device. Then, you run the Fault Injection Debugger from within the Intel Quartus Prime software or from the command line to simulate soft errors.

• The Fault Injection Debugger allows you to operate fault injection experiments interactively or by batch commands, and allows you to specify the logical areas in your design for fault injections.
• The command-line interface is useful for running the debugger via a script.

Note

The Fault Injection Debugger communicates with the Fault Injection IP core via the JTAG interface. The Fault Injection IP accepts commands from the JTAG interface and reports status back through the JTAG interface. The Fault Injection IP core is implemented in soft logic in your device; therefore, you must account for this logic usage in your design. One methodology is to characterize your design’s response to SEU in the lab and then omit the IP core from your final deployed design.

You use the Fault Injection IP core with the following IP cores:

• The Error Message Register Unloader IP core, which reads and stores data from the hardened error detection circuitry in Intel FPGA devices.
• (Optional) The Advanced SEU Detection Intel FPGA IP core, which compares single-bit error locations to a sensitivity map during device operation to determine whether a soft error affects it.

Fault Injection Debugger Overview Block Diagram

Notes:

1. The Fault Injection IP flips the bits of the targeted logic.

2. The Fault Injection Debugger and Advanced SEU Detection IP use the same EMR Unloader instance.

3. The Advanced SEU Detection IP core is optional.

Instantiating the Fault Injection IP Core

NOTE

The Fault Injection IP core does not require you to set any parameters. To use the IP core, create a new IP instance, include it in your Platform Designer (Standard) system, and connect the signals as appropriate. You must use the Fault Injection IP core with the EMR Unloader IP core. The Fault Injection and the EMR Unloader IP cores are available in Platform Designer and the IP Catalog. Optionally, you can instantiate them directly into your RTL design, using Verilog HDL, SystemVerilog, or VHDL.

About the EMR Unloader IP Core
The EMR Unloader IP core provides an interface to the EMR, which is updated continuously by the device’s EDCRC that checks the device’s CRAM bits CRC for soft errors.

About the Advanced SEU Detection IP Core

Use the Advanced SEU Detection (ASD) IP core when SEU tolerance is a design concern. You must use the EMR Unloader IP core with the ASD IP core. Therefore, if you use the ASD IP and the Fault Injection IP in the same design, they must share the EMR Unloader output via an Avalon®-ST splitter component. The following figure shows a Platform Designer system in which an Avalon-ST splitter distributes the EMR contents to the ASD and Fault Injection IP cores.

Defining Fault Injection Areas
You can define specific regions of the FPGA for fault injection using a Sensitivity Map Header (.smh) file. The SMH file stores the coordinates of the device CRAM bits, their assigned region (ASD Region), and criticality. During the design process you use hierarchy tagging to create the region. Then, during compilation, the Intel Quartus Prime Assembler generates the SMH file. The Fault Injection Debugger limits error injections to specific device regions you define in the SMH file.

Performing Hierarchy Tagging
You define the FPGA regions for testing by assigning an ASD Region to the location. You can specify an ASD Region value for any portion of your design hierarchy using the Design Partitions Window.

1. Choose Assignments ➤ Design Partitions Window.
2. Right-click anywhere in the header row and turn on ASD Region to display the ASD Region column (if it is not already displayed).
3. Enter a value from 0 to 16 for any partition to assign it to a specific ASD Region.
   • ASD region 0 is reserved to unused portions of the device. You can assign a partition to this region to specify it as non-critical..
   • ASD region 1 is the default region. All used portions of the device are assigned to this region unless you explicitly change the ASD Region assignment.

About SMH Files

The SMH file contains the following information:

• If you are not using hierarchy tagging (i.e., the design has no explicit ASD Region assignments in the design hierarchy), the SMH file lists every CRAM bit and indicates whether it is sensitive for the design.
• If you have performed hierarchy tagging and changed default ASD Region assignments, the SMH file lists every CRAM bit and it’s assigned ASD region.

The Fault Injection Debugger can limit injections to one or more specified regions. To direct the Assembler to generate an SMH file:

• Choose Assignments ➤ Device ➤ Device and Pin Options ➤ Error Detection CRC.
• Turn on the Generate SEU sensitivity map file (.smh) option.

Using the Fault Injection Debugger

NOTE
To use the Fault Injection Debugger, you connect to your device via the JTAG interface. Then, configure the device and perform fault injection. To launch the Fault Injection Debugger, choose Tools ➤ Fault Injection Debugger in the Intel Quartus Prime software. Configuring or programming the device is similar to the procedure used for the Programmer or Signal Tap Logic Analyzer.

Fault Injection Debugger

To configure your JTAG chain:

1. Click Hardware Setup. The tool displays the programming hardware connected to your computer.
2. Select the programming hardware you wish to use.
3. Click Close.
4. Click Auto Detect, which populates the device chain with the programmable devices found in the JTAG chain.

Hardware and Software Requirements

The following hardware and software is required to use the Fault Injection Debugger:

• FEATURE line in your Intel FPGA license that enables the Fault Injection IP core. For more information, contact your local Intel FPGA sales representative.
• Download cable (Intel FPGA Download Cable, Intel FPGA Download Cable II, , or II).
• Intel FPGA development kit or user designed board with a JTAG connection to the device under test.
• (Optional) FEATURE line in your Intel FPGA license that enables the Advanced SEU Detection IP core.

Configuring Your Device and the Fault Injection Debugger

The Fault Injection Debugger uses a .sof and (optionally) a Sensitivity Map Header (.smh) file. The Software Object File (.sof) configures the FPGA. The .smh file defines the sensitivity of the CRAM bits in the device. If you do not provide an .smh file, the Fault Injection Debugger injects faults randomly throughout the CRAM bits. To specify a .sof:

1. Select the FPGA you wish to configure in the Device chain box.

2. Click Select File.

3. Navigate to the .sof and click OK. The Fault Injection Debugger reads the .sof.

4. (Optional) Select the SMH file.
   If you do not specify an SMH file, the Fault Injection Debugger injects faults randomly across the entire device. If you specify an SMH file, you can restrict injections to the used areas of your device.

   • Right-click the device in the Device chain box and then click Select SMH File.
   • Select your SMH file.
   • Click OK.

5. Turn on Program/Configure.

6. Click Start.

The Fault Injection Debugger configures the device using the .sof.

Context Menu for Selecting the SMH File

Constraining Regions for Fault Injection

After loading an SMH file, you can direct the Fault Injection Debugger to operate on only specific ASD regions. To specify the ASD region(s) in which to inject faults:

1. Right-click the FPGA in the Device chain box, and click Show Device Sensitivity Map.
2. Select the ASD region(s) for fault injection.

Device Sensitivity Map Viewer

Specifying Error Types

You can specify various types of errors for injection.

• Single errors (SE)
• Double-adjacent errors (DAE)
• Uncorrectable multi-bit errors (EMBE)

Intel FPGA devices can self-correct single and double-adjacent errors if the scrubbing feature is enabled. Intel FPGA devices cannot correct multi-bit errors. Refer to the chapter on mitigating SEUs for more information about debugging these errors. You can specify the mixture of faults to inject and the injection time interval. To specify the injection time interval:

1. In the Fault Injection Debugger, choose Tools ➤ Options.
2. Drag the red controller to the mix of errors. Alternatively, you can specify the mix numerically.
3. Specify the Injection interval time.
4. Click OK.

Injecting Errors

You can inject errors in several modes:

• Inject one error on command
• Inject multiple errors on command
• Inject errors until commanded to stop

To inject these faults:

1. Turn on the Inject Fault option.
2. Choose whether you want to run error injection for a number of iterations or until stopped:
   • If you choose to run until stopped, the Fault Injection Debugger injects errors at the interval specified in the Tools ➤ Options dialog box.
   • If you want to run error injection for a specific number of iterations, enter the number.
3. Click Start.

Note: The Fault Injection Debugger runs for the specified number of iterations or until stopped. The Intel Quartus Prime Messages window shows messages about the errors that are injected. For additional information on the injected faults, click Read EMR. The Fault Injection Debugger reads the device’s EMR and displays the contents in the Messages window.

Intel Quartus Prime Error Injection and EMR Content Messages

Recording Errors
You can record the location of any injected fault by noting the parameters reported in the Intel Quartus Prime Messages window. If, for example, an injected fault results in behavior you would like to replay, you can target that location for injection. You perform targeted injection using the Fault Injection Debugger command line interface.

Clearing Injected Errors
To restore the normal function of the FPGA, click Scrub. When you scrub an error, the device’s EDCRC functions are used to correct the errors. The scrub mechanism is similar to that used during device operation.

Command-Line Interface
You can run the Fault Injection Debugger at the command line with the quartus_fid executable, which is useful if you want to perform fault injection from a script.

Targeted Fault Injection Feature

Note

The Fault Injection Debugger injects faults into the FPGA randomly. However, the Targeted Fault Injection feature allows you to inject faults into targeted locations in the CRAM. This operation may be useful, for example, if you noted an SEU event and want to test the FPGA or system response to the same event after modifying a recovery strategy. The Targeted Fault Injection feature is available only from the command line interface. You can specify that errors are injected from the command line or in prompt mode. Related Information

AN 539: Test Methodology or Error Detection and Recovery using CRC in Intel FPGA Devices

Specifying an Error List From the Command Line

The Targeted Fault Injection feature allows you to specify an error list from the command line, as shown in the following example: c:\Users\sng> quartus_fid -c 1 – i “@1= svgx.sof#i ” -n 2 -user=”@1= 0x2274 0x05EF 0x2264 0x0500″ Where: c 1 indicates that the FPGA is controlled by the first cable on your computer. i “@1= six.sof#i ” indicates that the first device in the chain is loaded with the object file svgx.sof and will be injected with faults. n 2 indicates that two faults will be injected. user=”@1= 0x2274 0x05EF 0x2264 0x0500” is a user- specified list of faults to be injected. In this example, device 1 has two faults: at frame 0x2274, bit 0x05EF and at frame 0x2264, bit 0x0500.

Specifying an Error List From Prompt Mode

You can operate the Targeted Fault Injection feature interactively by specifying the number of faults to be 0 (-n 0). The Fault Injection Debugger presents prompt mode commands and their descriptions.

In prompt mode, you can issue the F command alone to inject a single fault in a random location in the device. In the following examples using the F command in prompt mode, three errors are injected. F #3 0x12 0x34 0x56 0x78 * 0x9A 0xBC +

• Error 1 – Single bit error at frame 0x12, bit 0x34
• Error 2 – Uncorrectable error at frame 0x56, bit 0x78 (an * indicates a multi-bit error)
• Error 3 – Double-adjacent error at frame 0x9A, bit 0xBC (a + indicates a double bit error)

F 0x12 0x34 0x56 0x78 One (default) error is injected: Error 1 – Single bit error at frame 0x12, bit 0x34. Locations after the first frame/bit location are ignored. F #3 0x12 0x34 0x56 0x78 0x9A 0xBC + 0xDE 0x00

Three errors are injected:

• Error 1 – Single bit error at frame 0x12, bit 0x34
• Error 2 – Uncorrectable error at frame 0x56, bit 0x78
• Error 3 – Double-adjacent error at frame 0x9A, bit 0xBC
• Locations after the first 3 frame/bit pairs are ignored

Determining CRAM Bit Locations

Note:

When the Fault Injection Debugger detects a CRAM EDCRC error, the Error Message Register (EMR) contains the syndrome, frame number, bit location, and error type (single, double, or multi-bit) of the detected CRAM error. During system testing, save the EMR contents reported by the Fault Injection Debugger when you detect an EDCRC fault. With the recorded EMR contents, you can supply the frame and bit numbers to the Fault Injection Debugger to replay the errors noted during system testing, to further design, and characterize a system recovery response to that error.

Advanced Command-Line Options: ASD Regions and Error Type Weighting

You can use the Fault Injection Debugger command-line interface to inject errors into ASD regions and weight the error types. First, you specify the mix of error types (single bit, double adjacent, and multi-bit uncorrectable) using the –weight .. option. For example, for a mix of 50% single errors, 30% double adjacent errors, and 20% multi-bit uncorrectable errors, use the option –weight=50.30.20. Then, to target an ASD region, use the -smh option to include the SMH file and indicate the ASD region to target. For example: $ quartus_fid –cable=USB-BlasterII –index “@1=svgx.sof#pi” –weight=100.0.0 –smh=”@1=svgx.smh#2″ –number=30

This example command:

• Programs the device and injects faults (pi string)
• Injects 100% single-bit faults (100.0.0)
• Injects only into ASD_REGION 2 (indicated by the #2)
• Injects 30 faults
