When I create netlist by skill function of "createNetlist(?recreateAll t, ?display t)" in Cadence IC6.1.7, I get following netlist.

However Cadence Spectre show following warning.
Warning from spectre in `Dual_Hoge', during circuit read-in.
WARNING (SFE-2946): "input.scs" 314: `Dual_Hoge': Parameter `nf' redefines parameter of same name defined at higher level. Local parameter value will be used.

Further occurrences of this warning will be suppressed.

I want to pass nf=4 for "Rec0" and "Rec1" hierarchally.

What value is applied as nf for "Rec0" and "Rec1" hierarchally ?


If I create netlist from ADE, I get following netlist.

Cadence Spectre does not say warning of "Local parameter value will be used." for this netlist.

How can I create same netlist by "createNetlist(?recreateAll t, ?display t)" ?

Can you generate the ADE logFile (OCEAN ?). Perhaps you can find a hint therein?
