741 opamp in Cadence/SpectreS

[rush3k]

Hello,

I'm trying to do a simulation on the 741 opamp in Cadence. I have created some basic npn and pnp model files and put them in the model path, however I am getting some syntax error statements caused by the model files.

.model npn bjt type=\npn BF=125 Cje=.5p Cjc=.5p Rp=500
.model pnp bjt type=\pnp BF=25 Cje=.3p Cjc=1.5p Rp=250

Even when I do some adjustment, the DC operating point simulation shows that the devices are not working correctly, and further transient simulation produce no waveforms at the output.

Let me know if you've tried this before, or it you have a better way.

Thanks.

try put the model name at npn properties = Mn8H, pnp modelname = Sp10B12CH
