hii..i am using innovus...i wanted to replicate the same results using the same FP and same bounding of cells using region....but sometimes the result varies.
innovus is deterministic. I have never seen the behavior you are reporting. are you sure everything is exactly the same? are you loading a floorplan or drawing it by hand?
Those runs have same tool settings? Usually there might be some very small difference(not exactly the same, but in a close range) if design inputs are same and tool settings are same. It's due to heuristic algorithms used in tools that might not generate same results in different runs.
every single version of innovus I have tried is not heuristic, it has always been deterministic. I suspect the OP is doing something different every time.
