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]
*
* NMOS (3.3 Volts, 70A, NChannel)
