[SOLVED] Spectre simulation problem with 32nm IBM pdk: bsimsoi v4.3 is invalid

[chickenvlsi]

Hi everyone,
1. When I did a transient simulation (with an inverter design) in 32nm SOI IBM PDK, Spectre (version 6.1.3.500.14) issued the following warning:
- "Model parameter version =4.3 is not valid, reset to default model value = 3". - Then, I double checked the model version of the PDK ant it was bsim version 4.3. My question is that How can I fix the problem? Do I need to update my Cadence to newer version?
2. After Spectre issued the above warning, it terminated my simulation with this error: Error found by spectre at time = 30e-24 s during transient analysis `tran'. ERROR (SPECTRE-16192): No convergence achieved with the minimum time step specified. Actually, my design is very simple, just a inverter consisting of an nfet and a pfet.
I am wondering if this error is related to the above warning about model version conflict or not?
Could you please be as kind as to let me know what is wrong here ?
Thanks very much.
Regards,
Andy

Hello,

I got the exact same issue. Could you describe how you did solve it ?

Thanks a lot

edit : Okay hotfixed it. Changed the version of the requested files from 4.3 to 4.
Anyone got a clue why 4.3 is not working ? I'm running version 1.2.0.6 of the PDK and the release note says that 4.3 was implemented in 1.2.0.5

Btw the problem is the MMSIM version : BSIMSOI 4.3 is only supported since version 7.2 of MMSIM and I'm actually running 7.0
