Default Adding SPICE definitions to Microcap demo

Hi everybody!
I'd like to add this SPICE definition of a 2sK170 JFet to Microcap Demo. I fiddled for a while with the component editor, but I couldn't find the way. Is there any Microcap expert willing to help?
Thanks very much in the anticipation,
Massimo

Found another definition on the web.

.model J2sk170 NJF(Beta=59.86m Rs=4.151 Rd=4.151 Betatce=-.5 Lambda=1.923m
+ Vto=-.5024 Vtotc=-2.5m Cgd=20p M=.3805 Pb=.4746 Fc=.5
+ Cgs=25.48p Isr=84.77p Nr=2 Is=8.477p N=1 Xti=3 Alpha=10u Vk=100
+ Kf=111.3E-18 Af=1)


I think you just create a separate model file, import it as a parts library, then add a symbol definition. Is that part of Microsim? Didn't know they were around anymore.

Hi soongsc,
thanks for your answer. I use (I'd like to use) Microcap, not Microsim. In case, would you please detail where to find the commands you mentioned, how to create a model file and so on?
Thanks very much,
Massimo

Here's a guideline from MC6. Don't know if you can add models in the demo version though.
