thanks for relay. I try to use synplify_pro to generate .qvm, then use the netlist in quartus. but the route can not pass. when I use RTL, quartus route can pass, but when I use netlist, quartus route can not complete. do you have some suggestion about how quartus fit the netlist generated by synplify? thanks.
