Hello all,

I was wondering what the adce parameter in the Hspice model card was referring too. I have it set to the default 1 and I am getting a warning during simulation:

Warning: Acde = 1 may be too small in BSIM4 model pmos with w=9e-006 l=4.5e-008.

Can i just ignore this warning (thought I hate doing that)? This is a 45nm BSIM4 card. Thanks!

I'm facing the same issue here with a 32nm and a 22nm BSIM4 cards. Please let me know if you have figured this issue out!

Thanks,
