Hi,
I want to program ic "Actel a1020b"
Which framwork and hardware is used to program ic Actel a1020b...plz help me.

 

How do You know that You need this particular model of FPGA ?

This is a very advanced model, not for beginners.

If You have to ask how to program it, You need to start with a very basic model of FPGA,
then many basic questions will be answered,
and then You can advance to more complex programming.

This is an old ACT1 device
Actel FPGAs are now part of microchip

Programmers are found here

You can guess the age by the fact the recommended pc for the code is a 386 or 486 for the big ones !

I'd suggest you talk to microchip abotu what is still available,
