Design settings for correct board operation with a minimal design
For correct operation with a minimal design, the MPS3 board requires a minimum amount of RTL in the
FPGA, and certain variable settings in the
config.txt
file.
Minimum RTL
The following table shows the signals that you must tie off in the FPGA to generate the
minimum RTL for correct operation of the MPS3 board.

FPGA signal
Minimum RTL
MMB_IDCLK
Tie LOW
EMMC_CLK
Tie LOW
QSPI_nCS
Tie HIGH
QSPI_SCLK
Tie LOW

Configuration file settings
If the design does not implement the
Serial Configuration Controller
(SCC), you must set the
variable FPGA_SCC to FALSE in the board
config.txt
file.
If the design does not implement the MCC
‑
SMC interface, you must set the variable
FPGA_SMB to FALSE in the board
config.txt
file.
