Using spectre to do analog simulation

Is bsim3v3 the only valid Mosfet model of doing analog simulation in spectre?

Thank you.

Then RTFM ;-)

I don't of any simulator that doesn't at least handle CMOS model Level=1 up into the first versions of BSIM3.

what about tsmc25, level 49? It seems that spectre doesn't recognize 'NMOS' or 'PMOS' device.

"Level=49" is an HSpice designation. What does Spectre call it? PSpice calls it "Level=7"

Works just ducky in PSpice...

'Have you got experience with GUI's'

He said.

'Graphical User Interfaces Mate, not a problem'

I said.

Quick as a flash I shoved the requisite number of fingers down my throat and donated a palette of material to his 'desktop'.

'Stick your hands on that and be creative'.

Thank you, Jim. I checked the document of spectre, and found that it supports bsim1, 2,

3, 3v3, 4, and some other device models. it deos not have NMOS or PMOS deveice model at all, which means the tsmc25 spectre model (level 11)can not be used in spectre. So I will use bsim3v3 and see the results.

NMOS and PMOS are device TYPES. The actual MODEL will be supplied by the foundry, as in...

..model N NMOS Level=7 ; [Level=49 in HSpice]
