software for PCB LAYOUT

hi friends,
can anyone please tell me how can I genrate PCB LAYOUT for a circuit diagram, automatically. Actually, i've heard somewhere , there's a software in which if i draw the circuit diagram, the PCB LAYOUT is generated automatically. Please tell the version of the software also.

I'll be highly obliged if someone could guide me.

With best regadrs,
Amit

hi Amit, you should try out Eagle Layout Editor. a free trial version of Eagle can be downloaded from their website. a great number of hobbyists and students use Eagle for their projects.

the manual of Eagle is easy to understand and there are plenty of examples and tutorials for Eagle all over the internet.

you could also try PCB123 which is a completely free board layout tool. professional designers use a great variety of layout tools like Protel, Orcad etc but you shouldnt worry about that.
