Microsemi SmartFusion2 MSS Single Error Correct
Introduction
In radiation prone environments, storage elements such as RAMs and FIFOs are susceptible to transient errors caused by heavy ions. Errors can be detected and corrected by employing error detection and correction (EDAC). The EDAC controllers implemented in SmartFusion2 support single error correction and double error detection (SECDED). Memories protected by EDAC within SmartFusion2 are the eSRAMs, the USB internal memory, the Ethernet MAC transmit and receive internal FIFOs, the controller area network (CAN) controller internal RAMs, the PCIe FIFOs and the external DDR memories.
The values entered in the configurator will be exported into the programming
files for programming of the flash bits that control this functionality. The
flash bits are loaded in the system registers at power up (or when the
DEVRST_N external pad is asserted/de-asserted).
For complete details please refer to the Microsemi SmartFusion2 User’s Guide.
To configure the PCIe core use the High Speed Serial Interface configurator. For the Fabric DDR Controller use the DDR Memory Controller configurator. Both configurators are available from the Libero IP Catalog.
Configuration Options
Expose EDAC_ERROR Bus – Use this option to expose the EDAC_ERROR bus signal to
the FPGA fabric where it can be used by your design.
Enable EDAC – Use this option the enable the EDAC functionality for each of
the following blocks: eSRAM0, eSRAM1, Cache, Ethernet MAC TX and RX RAMs, USB
and CAN.
Enable EDAC Interrupt(s) – Use this option the enable the EDAC Interrupts for each of the following blocks: eSRAM0, eSRAM1, Cache, Ethernet MAC TX and RX RAMs, USB and CAN. You can chose to enable interrupts for 1-bit error, 2-bit error or both as shown in Figure 1-1.
Figure 1-1 • Enable EDAC
Enable MDDR ECC Interrupts – Use this option to enable the MSS DDR (MDDR) ECC interrupts (Figure 1-2).
