When I run DC synthesis (DC version : W-2024.09-SP1), the log has following message :
"Information: In design 'register_ctrl', the register 'A_reg' is removed because it is merged to 'B_reg'. (OPT-1215)"
But I want to keep "A_reg" and let "B_reg" is removed. How to set DC constrain?
I have try to set dont_touch for "A_reg" , but it still not work.
