Post Nestling Skill script

Hello.

Program:        @(#)$CDS: Virtuoso Studio version IC25.1-64b 02/10/2026 20:26 (cpgbld36) $
Sub version:        sub-version  IC25.1-64b.ISR4.49  (64-bit addresses)

I want to run a skill script after netlisting but before simulation (spectre).

I am having problems to register the skill function to happen post netlisting.

I am using

;; Register the function specifically to fire right before the simulation runs
hnlRegPostNetlistTrigger('Launch_PneavesNetlistHook)

But I get the error

generate netlist...
function My_WriteHierarchicalSources redefined
function Launch_PneavesNetlistHook redefined

Any ideas ? Thanks..
