General Description: The FPGA Scripting Tool (FST) implements a Tcl-based command-line interface for the FPGA Compiler II product, including FPGA Express. Can one use a compiler script command to specify the use of pullup resistors?
Assuming the top-level name of the chip as specified by the compiler directive:
set chip mychip
Then syntax is demonstrated below:
set_pad_resistance "PULLUP" "mychip/port_name"
Note that PULLUP must be all capitals, and the use of double quotes. For more information and sample scripts, please see the FST scripting guide help.
