With SkyWater PDK 130nm we have:
 - a number of special layers which mark various type of capacitors,
   resistors, inductors etc. Various oxide thickness markers likes
   high voltage are also used
- instead of lowes metal layer they are using that bloody local
interconnect layer "li" (I guess it must be hight resistive wolfram)


So I have questions how to describe several thing in Electric  tech file?:
 - how to describe that via4 connects metal5  to cap2m  if one (cap2m)
present and to metal4 otherwise?
 - how to describe that when metal1 is connected to active/diffusion
   the connection is NOT m1-to-active-contact, but that "sandwich"
   of *mcon*+*li*+*licon*, but *licon* is also independent "pseudometal"
layer
   which is connected to active with licon?
 - does Electric already have some facility for generating inferred layers
   in GDS output? I mean writing *mcon*+*li*+*licon* instead
m1-to-active-contact when writing GDS

Steven, could you give an advice on issues above, looking on their layers
map, please???

I also tried to ask the same question description of LIL for other
technology, this time I tied to provide more clear formulation
