Plexim RT Box controlCARD Interface-product

Introduction

The PLECS RT Box is a powerful real-time simulator based on a Xilinx Zynq system on a chip (SOC). With its digital and analog I/O signals, the RT Box is well-equipped for hardware-in-the-loop (HIL) testing as well as rapid control prototyping (RCP).
If employed for HIL testing, the RT Box typically emulates the power stage of a power electronic system. The power stage could be a simple DC/DC converter, an AC drive system or a complex multi-level inverter system. The device under test (DUT) is the control hardware connected to the RT Box. In such a setup, the complete controller can be tested without the real power stage.

To simplify the connection of external hardware and to provide convenient ac- cess to the RT Box inputs and outputs, Plexim offers a set of RT Box accessories.

The RT Box controlCARD I nterface described in this document has two con- trolCARD slots which facilitate a simple connection of the RT Box with the 100-pin and 180-pin controlCARD modules from Texas Instruments (TI). It enables users to test control algorithms implemented on C2000 MCUs without devel-oping their own interface hardware. The pinout of the controlCARD Interface board has been optimized for the following development kits

Piccolo controlCARDs (280049, 28027, 28035, 28075, 28069)
Delfino controlCARDs (28335, 2837xD)
Concerto controlCARDs (F28M35, F28M36)

The controlCARD Interface may also be used with other development boards compliant with the controlCARD pinout.

Interface Board Overview

The interface board provides a 100-pin socket for the older 100-pin control- CARDs, as well as a 180-pin socket for the newer modules. Fig. 2.1 shows the top view of the controlCARD interface board.

All RT Box output signals are buffered to protect the MCU from overvoltage, and local opamps provide a low-impedance source for the MCUs ADC inputs. The board provides access to three analog outputs labeled AOUT-13 . . . 15 via BNC connectors. For status communication with the RT Box, the board features four sliding switches and four LEDs labeled DIO-28 . . . DIO-31.

Additionally, external JTAG adapters can be connected to the MCUs by means of two 14-pin headers labeled JTAG-100, JTAG-180. Each controlCARD is wired to an isolated CAN driver, allowing communication among the control-CARDs as well as external equipment. The board also provides a 64 kbit Serial Electrically Erasable PROM for user specific purposes.

A 6-pin unshrouded connector labeled SCI for FTDI cable is provided to com- municate with older 100-pin controlCARDs which do not support serial interface.

ControlCARD Socket Pins

Tables 2.1 and 2.2 list the pin assignments of 100-pin and 180-pin controlCARD sockets and the RT Box signals.

A more detailed table, including the available processor functions at each pin for the supported controlCARDs, can be found in the Appendix.

Interface Board Overview

Plexim RT Box controlCARD Interface 01

Figure 2.1: RT Box controlCARD Interface Board

Onboard Voltage Supply

Power to the controlCARD interface board can be supplied in two ways, by selecting the appropriate jumper terminals on the bottom right corner of the board. One way is to supply power directly from the RT Box. The second is through an external source using the USB connector labeled 5V PWR . This al- lows the board to be used without the RT Box. The interface board contains a linear voltage regulator that steps down the 5 V supplied externally or by the RT Box to 3.3 V required by the controlCARD. A green LED on the lower right section of the board indicates power supply to the board.

Analog Output

All 16 analog outputs from the RT Box are routed to both 100-pin and 180-pin control card slots. It is possible to operate two cards at the same time, al- though the user must be aware that the sampling of one MCU could affect the measurements of the other. If both control card slots are populated, the ana- log signals must be shared by the controlCARDs. Three analog output channels AOUT-13 . . . AOOUT-15 are also accessible at the BNC connectors.

All 16 analog output signals are passed through a rail-to-rail CMOS operational amplifier signal conditioning circuit, as shown in Fig. 2.2, for scaling the volt-ages to 0 V and 3.3 V, and for protecting the inputs of the MCU from damage by over-voltage. This introduces a gain of 4.42 /6.8 (or 0.65) in between the analog output pins of the RT Box and the analog input pins of the controlCARD.

Additionally, each analog channel routed to the 180-pin controlCARD socket is buffered with a capacitor (2200 pF) against ground, to lower the source impedance of the channel so that the sample and hold capacitor of the MCU can be charged quickly. A small resistance (56 Ω) is also placed in series to stabilize the driving opamp circuit.

The 100-pin controlCARD socket is excluded from this step and receives analog output signals directly after signal conditioning, as these resistors and capacitors are already populated on the 100-pin controlCARDS.

Figure 2.2: Analog Output Signal Conditioning Circuit

Digital I/O

Digital inputs DI0 . . . DI15 from the RT Box are connected to the 180-pin controlCARD socket. DI16 . . . DI31 are connected to the 100-pin controlCARD

socket. Digital inputs DI28 . . . 31 can also be set via four sliding switches pro-vided on the board labeled DIO-28 . . . DIO-31.

Digital outputs DO0 . . . DO7 are connected to the 100-pin controlCARD socket. DO11 . . . DO14, DO16 . . . 27 are connected to the 180-pin controlCARD socket. DO28 . . . DO31 are connected to four LEDs in the upper right section of the board labeled DIO-28 . . . DIO-31.
All the digital input and output signals are buffered through bus transceivers to protect the inputs of the MCU from voltages greater than 3.3 V.

DO15 is connected to the 180-pin controlCARDs MCU reset pin via RST jumper. If the jumper is set a low-level output at DO15 will reset the MCU. Do not set this jumper unless you wish to use this feature. Alternatively, the MCU can be reset using the push button labeled RESET.

CAN Communication

Two electrically isolated CAN transceivers provide CAN communication that can be accessed through a 9-pin D-SUB connector on the bottom left corner of the board. This allows communication among the controlCARDs, if populated together, as well as with external equipment.

Table 2.3 lists the pin assignments of the 9-pin D-SUB connector, 100-pin controlCARD and 180-pin controlCARD sockets.

Note CAN_L and CAN_H signals on pins 2 and 7 respectively on the 9-pin D-SUB connector can be terminated with a 120 Ω resistor using the jumper labeled CAN TERM located on the bottom left corner of the board.

JTAG Headers

Tables 2.4 and 2.5 list the pin assignments of JTAG headers for the 100-pin controlCARD labeled JTAG-100 and 180-pin controlCARD labeled JTAG-180 respectively.

100-pin| CAN Transceiver 1| 9-pin connector| CAN Transceiver 2| 180-pin
