Hello

I am new in PLD so my questions may seem stupid...
If it's a case, appologize for them.

There are my questions:
1. Is there a possibility to generate .jed file from OrCAD.
2. If it's possible how to use Atmel chips. When I run Programmable Logic Project Wizard in OrCAD, there is no Atmel vendor. Only Actel, Altera and Xilinx.

Thanks in advance.

Pavel.

No. You would use a thrid party utility to compile your equations to a jed.

If you are using simple PAL's/GAL's, use http://elm-chan.org/fsw/fgal.zip

Really Orcad FPGA are for legacy designs. You would require third party tools to use Orcad FPGA and I don't think Atmel is supported.

Mainly Orcad is now used for schematic capture and layout. So you will design your PLD in some third party tool, (usually vendor provided), create a schmatic representation (in orcad) and create the PCB with Orcad Layout.

If you have simple Pal's/Gal's, you can simulate your design with Orcad Pspice.
