HOW DO I REMOVE THESE WARNINGS.I HAVE DESIGNED A GENERALIZED CODE FOR 4X4,8X8,16X16.ARRAY SIZE VARY FOR EACH CODE.
My code has warnings in synopsys design vision.Does due to these warnings will my report for area and power be affected.pLS HELP.

Hi,

You should post this question in ASIC Design group.

My opinion:

Put the signals in the sensitivity list (always block).

If you put the signals in the sensitivity list (to remove the warnings), the area and power will be different, but I'm not sure how much different it will be.

Thanks.

The area and power usage will be the same when you fix the warnings because synthesis always ignores the senstivity lists. But the final hardware wont match the simulation results.

Yes that's correct and I was wrong. So ignore my first reply.

Thanks.
