How to know the speed grade of a FPGA?

转到解答
Hi, Now I have a xc7k410t FPGA, but on the chip top there is no speed grade mark, so I want to know how to get the speed grade of the chip. Thanks.

1. By keeping good practices for traceability

2. As a crude approximation, by having something running at increasing clocks and checking the max freq it runs without errors

Uhm,

If the printing on the top is "not as expected",
that's a very good sign the part is counterfeit,

Can you take a picture and post ?

Hi @zhikai ,

 

According to ug475 page330, your device doesn't have the forth line in the marking definition.

Ask your vendor or download "Xilinx Go" APP in your phone and scan the 2D Barcode to get this infomation.

Just a note on the 2D scanner ,

If you have not used it in the last week
you will have to re register to use the app, and that can take two days to get approval or not through !
