I'm trying to simulate bits of my design under linux), and having trouble getting started.

I have NGSpice in Fedora 18's Electronic Spin, and it's obstinate :-/. I drew the circuit in it's schematic thing, but it seems to be refusing to update the netlist, and can't pick up the components I have in there. It only finds crap. There is gigabytes written about it, mostly irrelevant. I tried LTSpice under wine, but it doesn't seem any better.

I have a 10Mhz tuned LC network driving a HEMT (which appears in the simulation as a 10pF & 50k to ground) and I would like to be able to finely tune the input pulses and optimize it for 9.6Mhz - 10.4Mhz.

Is there a good guide to getting started? Should I be using some other flavour of Spice? I am restricted to OSS software ATM, as I run linux, and have no company buying m$ licenses behind me.

 

Found some stuff in the useful websites. Surfing off there now.

 

I'm familiar with LTspice. What type of problems did you have with that? Could you simulate their example circuits?
