I don't know if there are better advices from Jiri,but I solved this Post-Layout Simulation problem by myself. I added Reset pins for each register.(Especially...
Thank you Jiri. From what I see now in DDD, the content of my "IO area mapped" variables are bad. In section 7.8, it is written that whatever the SRAM mode is,...
