Design compiler critical range

Specify critical range – If no critical range is specified, design compiler works only on worst negative slack(WNS) end point in each path group. ie, It works only on WNS. But if we specify a critical range say 0.5, then it works on all paths in that clock group with slack below 0.5 ns.

Yes, dc_compiler will focus on paths that are at the critical range value or less. The weight option is also used to provide priority. Oct 3, 2011#3L
