Hi,
I need trouble shooting help in cdsSpice!!!

My netlist.c file
=================
*nmos transistor amplifier
..include "./FILE.m"
vin 1 0 ac 1 sin(0.8 0.7 1G 0.0 0.0)
vdd 4 0 dc=3.3
R0 4 2 100
c0 2 0 1.1p
m1 2 1 0 cmosn
..tran 0.25ns 10ns 0ns

My amp_mc.s
===========
sim netlist
keep all
sweep time from 0ns to 200ns by 10ns
go
get tran
loop y from 0 to 200 by 10
set time=y
print v(2)
endloop

As you can see I am just trying to print the transient o/p
voltages at different points in time!
The error I am getting is with respect to the model file that
I have included which is a tsmc 0.18u level 11 model.

The simulator doesnt recognise many of the model parameters
like UC, U0 etc!!

ERROR OUTPUT:
============
SPICE2 EXECUTION ...
0*ERROR*: NODE NUMBERS ARE MISSING
CHECK LINE 3 IN THE SPICE INPUT FILE
(EITHER cdsSpiceFinal OR THE GIVEN SPECIFIED GO FILE)
0*ERROR*: MUTUAL INDUCTANCE REFERENCES ARE MISSING
CHECK LINE 5 IN THE SPICE INPUT FILE
(EITHER cdsSpiceFinal OR THE GIVEN SPECIFIED GO FILE)
.....
.....
and so on

0*ERROR*: UNKNOWN DATA CARD: U0
CHECK LINE 9 IN THE SPICE INPUT FILE
(EITHER cdsSpiceFinal OR THE GIVEN SPECIFIED GO FILE)

The model file is according to the cdsSpice conventions like
no space b4 an "=" symbol
& to represent continuation..etc!

Please let me know where the problem is and what should
be done!
