file you are trying to simulate, so we can investigate the problem.Juan Andres

. You did specify L=.... L=...
in the mos transistor instead of L=... W=...
I have set L=0.15 W=1
. W=0.35 is too small, so use something bigger. See also chapter 31 of the ngspice manual to know how to save internal currents / voltages / parameters (like gm) of your simulations. Of course change the .lib according to your skywater installation.Matt Venn

05/28/2022, 3:08 AMOnly the high to low level-shifters are functional at 1v (sky130_fd_sc_ls__lpflow_lsbuf_hl_*)
But where do I find this? I installed sky130_fd_sc_ls through open-pdks and I can't find this cell, and its not in the skywater repo itself it seems. Is there another place where I should be looking? Thanks!

I am not sure whether these errors are related to my sky130_fd_pr__res_xhigh_po_2p85
. The related spice code in my extracted file is like:
.subckt sky130_asc_res_xhigh_po_2p85_1 Rin Rout VPWR VGND a_2148_115#

Would you mind giving me some hints about this error? Thanks a lot!Ryan R
