Running time with VCD annotation

vaswan

Hi all,

   'm running  a design (size of 250 K) for dynamic  low power analysis with VCD annotation 

and took huge amount of running time.

Running with Saif annotation went fine with lesser running time.

But when VCD file annotated with design(RTL) it took nearly two days and still it was not completed.

Can anybody give  the reason why it takes quite lot of time ?

    I sometimes have had trouble with this using the VCD also. Make sure you use a small window of time for analysis. Try using a Start and Stop time that contains only a few clock cycles. I sometimes still have trouble where the tool hangs. If this happens, try shutting down the tool and restarting. If you still have trouble, try using a different version of the tool.
