Voltage at Collector of NPN less than Minimum allowed for High
NPN datasheet says



So worst case drop IR= 500n  delta V= 0.5uA*0.1M = 0.05V drop from 1.8V  so ??? mystery leakage.

We cannot look any deeper without your SCH file.

Very primitive buggy Editor. It reads 0V out ?? with erroneous Exponent.



Definitely a fault in  LIB Model file...
I edited SCM macro file to change C:\user\willi... to  H:\Downloads\DTC144EET1.LIB    

Incorrect transfer function
