[moved] TDDB simulation using hspice

[Kelvintlai]

Hi

I am trying to simulate reliability stress effect using hspice, I can simulate hci/bti effect (.mosra) by looking at id degration (.mosraprint). Can anybody advise me how to simulate TDDB in hspice, and what parameter I can check? (I can't find it in hspice manual).

Thanks!

Maybe during last four years something changed, but at 2012 only BERT was allowing to simulate TDDB and only in very limited way.

Hi

I am using hspice (K-2015.06). I saw the command .mosra in the manual having the parameter tddb, and the foundry said their hspice model support HIC/BTI/TDDB.

May be I need to use BERT together for TDDB and not hspice alone.
