Hi does anyone know what is the layer scpmoshvt?, And with what layers do they form it?
m
Copy code
templayer pfetarea DIFF,barediff
 and POLY
 or baretrans
 and-not NSDM
 and-not HVI,hvcheck

...

 layer scpfet pfetarea
 and-not LVTN
 and-not HVTP
 and STDCELL
 and-not COREID
 labels DIFF

 layer scpfethvt pfetarea
 and-not LVTN
 and HVTP
 and STDCELL
 labels DIFF
diff AND poly NOT nsdm NOT hvi NOT lvtn AND hvtp AND stdcell Thin-ox pfet with high Vth in standard cell region.

Thanks

That's the definition, but the underlying concept is that SkyWater allows tighter DRC rules for contact-to-gate inside their own standard cells, and for magic to be able to handle the DRC rule separately, it has to separately distinguish a FET inside a standard cell vs. a FET outside a standard cell, which is why there is a type "scpmoshvt" and also a type "pmoshvt".

which layer should be joined to create?
t
If you're trying to create a device
scpmoshvt
, then you are generally advised against it---use
pmoshvt
and comply with the standard contact-to-gate rule. If you insist on creating such a device, then use
tech unlock *
so that you can draw it.
