I have a weird problem: In creator 4.3 I have a simple test circuit: 2 connected DFF's. DFF2 (d input) is connected to the output (q) of DFF1. DFF2 out is connected to an output pin and the circuit is clocked at 2Khz. The circuit builds without any problem when the 2 DFF's are not connected. When the 2 DFF's are connected, the build halts at Tech Mapping and takes 602 seconds to finish. This issue is related to my pc (win10). Running this test circuit on another pc: no problem in building and compiling. I have already uninstalled and reinstalled creator 4.3: problem is still present. Can you advise me on this issue.
