Software
Hi :lol:
If you need some programs for free, I'll say ExpressPCB or PSpice
ExpressPCB =
www.expresspcb.com
Advantages - Easy to use and learn
Disadvantages - Not as beautiful as other programs
PSpice by Orcad = **broken link removed**
Advantages - Makes good simulations (AC Sweep, bias), is used by the big companies like Philips
Disadvantages - Hard to learn while it has that many functions
Good luck in your searching
Just reply, if you thought of something else
