Re: What software do you use for PCB with FPGA ?

There are a wide range of tools with price tags from low to very high.
As yet I have not been convinced that an autorouter can do as a good a
job as a good human. Every board in our product is hand routed
including large boards e.g. our mini monster Broaddown4 -
http://www.enterpoint.co.uk/moelbryn/broaddown4.html. Whatever
autorouter you use it will probably cost you extra layers and / or
vias and that's board cost. On the other hand it may be quick to get
to the first board back to assembly but my experience with people that
go this way is that the board ends up being modded and pcb updated
several times costing more in the end. Hand routing is very close up
and personal and often mistakes are spotted during hand routing of
boards. So take your choice of tools and method and enjoy.

Hi Gabor,

I don't know what your budget is, but if you're completely
inexperienced and have the money, you may want to consider
using a design service.  We use a local service who consistently
gives us the lowest price on design projects.  

I have some experienced with OrCAD, only two layer, manul route
processing never used autoroute.

He uses PADS
software and only autoroutes non-critical nets.  I have
the PADS viewer which allows me to check his design output
and run off Gerber files for production.  A full seat of
PADS (without autorouting) starts around $5,000.00 but
you can get a free evaluation copy that is limited in
the size of design you can produce, if you want to play
around with it first.

PADs software from Mentor Graphics ?

I have to start a new project with an FPGA, therefore you must use a
multilayer PCB. I was wondering if anyone of you use systems, with
automatic systems routing. I do not even imagine how you can manually
route 600 or more tracks on multilayer PCB.
