Circuit simulation and PCB software

[fritz]

Can anyone recommend a good CAD program(s) for circuit sim (SPICE)
schematic and PCB layout ?

Preferably free or non-crippled shareware.
I only need the sim to work up to about 5Mhz or so.

Cheers !

LTspice is a very popular simulator:

Autotrax PCB is freeware, if you don't mind using DOS

It is quite well behaved under 98SE, and presumably would be under ME if anyone
is silly enough to be using that. In a VM under XP? Dunno.

Works OK for me.

LTSpice is free from Linear Technology and there is a very good 3rd part
Yahoo group for questions and answers ans spice models when you register.

KICAD is an open - source schemati capture and PCB program....

Google these for down loads

David has the right idea. I, too, recommend LTSpice. As good as you'll get,
at the right price: 0$

Hi

I want to simulate a circuit consisting of PowerPC processor and FPGAs
as main components. Is it possible to verify the schematic and
functionality of all the components in some CAD tool like LTSpice etc
before getting all the things stuffed on PCB? or i am thinking
science fiction ?
