[moved] BSIM4 model, HSpice to Pspice

[Ghurki]

Hello,

Why BSIM4 Mosfet model is called level=8 in Pspice and level= 54 in Hspice ?? Why different names for Hspice and Pspice ???

If I have Hspice model as given below, can I use the same model, as it is, in Pspice. I only need to change the level = 8 in Pspice. Right ??

*****************************************************************

.model nmos nmos ( level = 54

+version = 4.0 binunit = 1 paramchk= 1 mobmod = 0
+capmod = 2 igcmod = 1 igbmod = 1 geomod = 1
+diomod = 1 rdsmod = 0 rbodymod= 1 rgatemod= 1
+permod = 1 acnqsmod= 0 trnqsmod= 0

* parameters related to the technology node
+tnom = 27 ..... )

**************************************************************

I am new to Analog Design. Kindly someone explain it in easy words.

Thank you for the help.

I think it was just to maintain serial order of LEVEL in Pspice.
For example, LEVEL6=BSIM3-version 2.0
LEVEL7=BSIM3-version 3.2
Next version is BSIM4 which naturally got LEVEL8.

I believe you should be able to simulate hspice model in pspice with change in level. If there are some unsupported parameters or limitations, that should be there in pspice documentation.
