    [moved] Routing signal like clock tree in Cadence Encounter

    I need to route scan_en signal as clock tree network in Cadence Encounter, so that it reaches all scan flops with minimum skew.

    You sure you need this? Scan enable is not supposed to toggle like the clock, skew should not be an issue. Hold it high for a bit, submit all the test vectors you want while it is stable. No skew problem.

    It doesn't toggle like clock, this is right .. but it's highly loaded, it's supposed to reach every flop in the design , so it need to be buffered such like clock tree

    buffering is easy, the tools will take care of it automatically. you don't need to do anything special.
