Broadly fine, though a bit bloated? You may use https://github.com/fossi-foundation/nix-eda/blob/main/nix/netgen.nix as a reference which is a simpler derivation we've been using since 2013 2023, albeit, we don't support X11 so you have a strict upgrade in terms of that.

Thanks for reviewing.
I applied all your suggestions.

Some patching might be necessary. When I run the executable I get:

bash: ./results/netgen-vlsi-x86_64-linux/bin/netgen: /bin/bash: bad interpreter: No such file or directory

That's weird:

gonsolo nixpkgs:nix build .#netgen-vlsi
gonsolo nixpkgs:./result/bin/netgen -batch
Netgen 1.5.314 compiled on Sat Jan 10 10:55:32 UTC 2026
Warning: netgen command 'format' use fully-qualified name '::netgen::format'
Warning: netgen command 'global' use fully-qualified name '::netgen::global'

Without -batch it opens a window. No error here.

Do you have an idea why we get different result?

I added wrapProgram. It should work now.

I don't think it's a matter of wrapping. You should try using patchShebangs instead: https://nixos.org/manual/nixpkgs/unstable/#patch-shebangs.sh

I tried various variations of patchShebangs; nothing worked. EDA tools are notorious for their creative Makefiles.
I opted for a sed script instead. Are you ok with that @GaetanLepage?
