We have tried to use Expeditionpcb builtin DFF to check design, but not successful. We still use Valor to Validate PCB design. We have established Valor cluster to automatically run batch check and We developed tool to crossprobe betwen Valor report(html) and Expeditionpcb. A snapshot for crossprobing see below.
Are you using the builting DFF to replace Valor? How do you think Expeditionpcb's Builtin DFF?
