Dr. Edward Doering Department of Electrical and Computer Engineering Rose-Hulman Institute of Technology Last Update: 7 Jan 2008

Instructions:
Step 1: Enter Verilog port names in Column A (replicate name for bit vectors) Step 2: Enter bit number in Column B (leave blank for single-bit signals) Step 3: Copy *all* auto-generated text from Column C and paste into UCF file WARNING: Double-check to ensure that ports defined as outputs on your design connect ONLY to devices labeled as "output" in the "FPGA I/O Type" column! If you do not understand what this means, then ask your instructor for help. Failure to heed this warning will likely cause permanent damage to the board!!

Steps 1 and … 2:
Signal Name
