in my .v file i write a multuiplier(8*8), when i do functional analysis,the result is correct, but when i do gate-level analysis,the output result is uncorrect,what is the matter?
0x06 * 0x04 = 0x18 (functional)
0x06 * 0x04 = 0xX8 (gate_level)
and after gate-level analysis,i got a mult-8-8-0.db file
can you try initializing all registers before you start the simulation run. Basically make sure all flip-flops have some valid value (0 or 1 NOT x) at the beginning of simulation.
The x can also appear if you have multiple drivers for the same signal.
