obsolete FPGA design migration possible without Source code?(Ex Spartan-2)

Jump to solution

 

Hi Xilinx,

 

        I  Am using Spartan-2 FPGA for my older project. Now it is required more number,  as of now This part is Active so no issue, But in future if suppose this Spartan-2 gets obsolete then how to address this issue.

 

   Since this is older project we doesn't have any source code and functionality of the FPGA. we have only Programming file(Bit file/Bin file). If Xilinx helping on this it is very useful.

 

Thanks With Regards,

Venkatesh Babu.N

The bad news is that you're essentially going to have to recreate the design from scratch. There is no newer device that is bitstream-compatible (or even pin-compatible) with the Spartan 2, and there is no software that can modify the bitstream to work on a newer device.

 

The good news is that you've found the issue early enough to actually deal with it - rather than panicking when Xilinx sends you the "product is no longer available" email. Xilinx gives you a two-year notice period. They'll announce that they're planning to stop production, then a year later they'll announce that you need to place final orders for the parts, and then a year after that they stop accepting any orders for those chips.

 

I would suggest taking the opportunity to investigate how the system could benefit from a newer chip. Many old designs had an FPGA, a dedicated processor, maybe a dedicated DSP, etc. These days a single integrated chip like a Zynq can do all three roles, for much lower cost and PCB space.
