request for spec of hardware side

[ray-mahong]

Hi wujian100 owners, thanks for your contribution to open the source code of wujian.
But I met some trouble when I want to know more about its architecture or details inside.
Could you release some document like instruction set(ISA) and illustration of module level inside it ?
It looks like a user guide for software engineers more than for hardware engineers in the folder of doc.

when i saw the user guide ,I had the same feeling like you. The guide focuses on the software more than the hardware. And I wrote the #43 issues 10 days ago. nobody have replied me. This project seems to be unmaintained.

That's too bad. You know I'm interested the RISC-v and willing to study some in practice. If you know more project like it, please contact me.

@ray-mahong
If you want to study how to design risc-v core, I advice you to have a look at

ariane
rocket-chip
scr1
picorv32
darkriscv
and so on...

It seems that this repo fouces on how to design/use a SoC platform, so the core itself is not the key part.

thanks for your responses, I agree with you. I'm willing to study the list you gave.
