Step 3: Generate .mcs configuration memory file using Vivado batch mode.
|
|
|
|
Calls Vivado with step3_write_mcs.tcl (located in the same scripts/ directory)
|
|
via -tclargs so no temporary script files are created.
|
|
|
|
Usage:
|
|
python gen_mcs.py \
|
|
--vivado-dir "D:/Xilinx/Vivado/2018.1" \
|
|
--bit-file "E:/project/RU_golden/RU_golden.runs/impl_1/RU_golden_top.bit" \
|
|
--mcs-file "E:/project/RU_golden/RU_golden.runs/impl_1/RU_golden_smod.mcs"
|
|
|
|
Exit codes:
|
|
0 = success ("write_cfgmem completed successfully" in output)
|
|
1 = failure
