Timing Seen Different in ICC and DC

[sputty6]

Hi All

Am working on a design synthesised in DC topographical mode. The netlist obtained is loaded in ICC and i see different (aditional) timing violations which DC did not report. Colud anybody can tell me what might the reason for this behavior???


Thank U

If you loaded in ICC just netlist - the difference may come from different placement. DC in topo mode made one placement, ICC did another virtual placement, so the distances between cells are different, so timing is different.
