+"""
+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
