Web1 May 2011 · The Setup, Hold, Recovery, and Removal analyses report the logic depths of the top X paths by slack. Topology analysis reports the logic depths of the top X paths by logic depth. Paths: Specifies the number of paths to display by endpoint and slack level. The default value for Report number of paths is 10, otherwise, the report can be very long. Webnote: mainly try to improve setup slack in preplacement, inplacement and postplacement optimization before cts stages and in these stages neglecting the hold slack. in post placement optimization after cts stages the hold slack is improved. as a result of cts lot of buffers are added.
