Looking for Guidance on Bitcoin Development with eFPGA

I've been getting into Bitcoin development and I've hit a snag. Right now, I'm working on a project that involves using eFPGA to make some parts of the process more efficient. But I'm struggling a bit with how to handle the connection between the Bitcoin code and the eFPGA. I'm not going for anything too fancy, just wanting to try out a few specific functions. Has anyone here had experience with eFPGA in a similar situation? I could really use some advice or resources to help me figure this out better. Would love to hear about any hurdles you encountered or things I should be cautious about.

What exactly are you trying to build that requires an eFPGA?

FPGA was used to mine Bitcoin, but it was more than a decade ago. Other than that, i don't see anyone actually use FPGA for other Bitcoin-related tasks. Even cryptography verification performed by full node and SPV client still use CPU. There's possibility we're seeing SEO spam, which means he's not trying to build anything. But i can't be 100% sure about it.
