Need for Built-In Self-Test for FPGA code VHDL

[lahrach]

Hi friends,

I search vhdl code for BIST dedicated to test FPGA

Is there somme documents or tips!

regards!

lahrach,

Far as I know, BIST is mainly used on ASIC's. What is it you wish to test for once your FPGA is loaded and running?
Or do you wish to test RAMs before letting the application run? Usually BIST is used on RAMs in ASIC's.

A BIST circuit is usually just a write/read sequence to test that the bits in the RAM all work. BIST can be aplied to logic as well, but there needs to be a way to read the results and confirm correctness. Much of logic of a device is tested in the fab through JTAG chains.

Sckoarn,

Thank you for these explanation , I ask if you have some detailled documents about BIST

best regards,

lahrach,

A simple web search will give you lots of links in info

Built-in Self Test (BIST)
Built-in self-test - Wikipedia, the free encyclopedia

Here is a couple.
