Hello all, The bulk of the xhigh_po resistor is it connected to VDD or GND?

xschem is agnostic about this, as is the SkyWater spec. Magic draws only a device over substrate, but I could easily extend the parameter set to include drawing nwell underneath.
In fact that's probably worth doing right now. . .
Okay, done. Now you can specify either substrate or nwell under the poly resistor, and create a guard ring in the generated device for either one. Strictly speaking, there is no actual relationship between the voltage connected to the terminal and whether it is a well or substrate, although normally you would tie nwell to power and substrate to ground.

many thanks @Tim Edwards
