FPGA Mounting

I prefer to choose an appropriate way of mounting a FPGA based on the target application (if there is any). If the purpose is evaluation of FPGA in general, using an existing Dev Kit is probably the best solution. If you have an application, it sets constraints of size, power, costs and also the requirements as pin count and amount of LE. If ever possible, I would design a prototype that has a form factor near to the final application board. In an early design stage, a submodule of the target application can be extracted for evaluation.

Thanx semifnordic.That looks optimistic.Will try to do in this way.

If you are intent on using a prototype board (I assume you mean something like a breadboard or perfboard?), you have a few options. PLCC sockets with through-hole leads can be found, and this is certainly a viable option...especially if you are not experienced in soldering fine-pitch parts, as they are easy to damage! If you are confident in soldering, but simply want the part broken out to a larger pitch, try this company: http://www.schmartboard.com/ I have never used their products, but they appear to make what you would need if you wanted to break out, say, a TQFP package.

Thanx for answers cms and bpadalino. Should I use prototybe board and FPGA packaged in sockets with thru-hole technology pins? Can I put FPGA in Package with pins and then put it in prototype board?

for modern FPGA anwer is no. Now smallest fpga (and cpld too) in the best case are packed into TQFP with step 0.5-0.8mm that's hard to hand soldering without solid expirience. In the past were some attempts to use socketing for a FPGA, for example PLCC, but it was many years ago.

FPGA's are complicated devices. You're better off purchasing a starter board that has a working layout and design with some prototyping pins than trying to work out something yourself.
