Thank you for the quick check and for confirming the problem. I am glad I could help.

Thank you. I found a test case that does not need the foundry model card. The model card has one line, and all other parameters have default values. The problem is not related to binning.

Thank you. Here are the answers BSIM4 version The models are TSMC 65LP, LEVEL = 54, VERSION = 4.5. I cannot post the foundry model card (NDA). The result does not depend on the version: VERSION = 4.6.5, 4.7 and 4.8 give the same ngspice result. How much the values differ Single NMOS, L = 0.65 um, W = 10 um, NF = 1, SA = SB = 175 nm, SD = 200 nm, VGS = 0.6 V, VDS = 1 V. The other simulators select bin nch.3, ngspice selects nch.8. The ngspice result is the same with both bins, so I set nch.3 in all...
