I am building a course around the Cu V2 + IO boards, but I want to use the APIO toolchain so that it can connect to Logisim. APIO has an example for the old Cu board. I was planning to reuse that example, but does the constraints file need to be updated? If so, would the merged constraints file from Alchitry Labs V2 IO v2 demo work as a starting point to synthesize the verilog to the v2 boards? Thanks!
