[Ngspice-users] .lib as in hspice

[Rui T. <rm...@un...>]

Hi,

In HSpice I use the ".lib" command to include the BSIM3 model card 
files, with the foundry tecnology parameters, into the circuit 
simulation file *.sp. Below is an example of a spice file:

* ===================================================
1 single stage for test purposes


.lib 'm180.lib' TT

.options TNOM=27.0
.options ACCURATE OFF VNTOL=0.000001 RELTOL=0.01
.op all

Vvdd vdd vss 1.6v
Vvss vss 0 0.0v
Isrc n0 vss 20uA

Vvref n1 vss 0.52v

m0 n0 n0 vdd vdd P_18_MM w=9.4u L=2.0u
m1 n2 n0 vdd vdd P_18_MM w=47.0u L=2.0u
m2 n2 n1 vss vss N_18_MM w=34u L=1.2u

.tran 0.1ns 2us
.print tran v(n1)
.end

* ===================================================

When I try to simulate the previous file with Ngspice, it generates an 
error regarding the command ".lib" ... doesn't recongize it.

How can I "include" the BSIM3 model card files, with the foundry 
tecnology parameters in Ngspice netlist file?

Thanks in advance,

    Rui
