Hi all, what is the recommended way to use the resistors in xschem/magic and have the design pass LVS?  I was using the `res_high_po` version in my simulations as it allowed to change both the width and length easily, but I find now that magic extracts the resistors using the more specialized  `res_high_po_0p35`  model which causes a mismatch in LVS.  Updating the schematic in xschem got me a bit further but now I get a complaint from LVS that xschem adds a W parameter for the model which isn't there in the magic output.

```Netlists match uniquely with property errors.
sky130_fd_pr__res_high_po_0p35_ZSD4RR_0/sky130_fd_pr__res_high_po_0p35:11 vs. res_high_po_chain_13:R2/sky130_fd_pr__res_high_po_0p35:R[1]:Property W in circuit2 has no matching property in circuit1```

Ah, nevermind, I just figured out that my replacement of the resistor models wasn't complete.  The detailed model version works now!

Good to know that you got it working.  Let me know if you have any other issues.

Netgen LVS: Pass :white_check_mark: ─ so time for some more post-layout characterization now
