Get certain layers independent of technology node

Hi, I'm looking for a way to collect information about different groups of layers ("active", "metal", etc.) in order to display them. I already have a rich set of bindings for this purpose, but this is bound to a specific technology node, where I know the names of the layers. Is there a way to collect this information automatically? I already managed to draw something up regarding the vias and the metals (with techGetTechFile and sorting based on the material parameter).

Thanks in advance, kind regards,

Patrick

This code (output is in italics):

procedure(CCFgetLayersWithFunction(tf function)
mapcar('car setof(layerFunc techGetLayerFunctions(tf) cadr(layerFunc)==function))
)

tf=techGetTechFile(ddGetObj("gpdk090"))
db:0x2697db1a
CCFgetLayersWithFunction(tf "metal")
("Metal1" "Metal2" "Metal3" "Metal4" "Metal5"
"Metal6" "Metal7" "Metal8" "Metal9"
)
CCFgetLayersWithFunction(tf "cut")
("Cont" "Via1" "Via2" "Via3" "Via4"
"Via5" "Via6" "Via7" "Via8"
)

The function can be various things - e.g. nwell/pwell/ndiff/pdiff/nplus/pplus etc. Documented here: https://support.cadence.com/apex/techpubDocViewerPage?path=ascitechfile/ascitechfileIC6.1.8/chap4.html#pgfId-958082
