I'm a riscv hobby and personal researcher in China mainland Shanghai, day job is Software Tech Expert. I study Rocketchip generator code for about one year. the study process is lone, as no body I can talk to about it, for questions and for sharing. one day, I've seen cnrv.io and learned you guys are pushing and spreading riscv in China. so I'm wondering whether there is a way to communicate with you guys for question or sharing expierence with each other?
Right now, I'm trying to port rocketchip to fpga board as a pure softcore(without any arm core), and use on board DDR3 as external-RAM with my own memory controller(via AXI4 or tilelink it). at last
- [ 1] booting upstream Linux/GNUs.
- [ 2] running bare-metal code.
- [ 3] running Android. on it.
now, I've learned how to:
- Run Rocketchip generator.
- Elaberate firrtl to verilog.
- run firrtl interpreter or REPL to debug/diag FIRRTL issue. (because of this, had pushed a tiny contribute to firrtl intepreter repository for cross platform path issue.)
- design simple curcuit with Chisel3.
- write poke-peek tester code to test chisel curcuit.
I'm now focus on the Diplomacy and Tilelink part. however, the code is very free-style, which make it very hard to understand. but, the negotiation principle of the diplomacy package is highly agreeable. The TileLink is also a good implementation of coherence, with scalability. I'm willing to dig it deeper, and would like to exchange idea about it.
I'm enthusiasm for riscv, and willing to join any community, discussion, working oppotunities related to it.
Have you noticed that I have commented many diplomacy codes in https://github.com/cnrv/rocket-chip-read?
I believe @xfguo would contact you soon to add you into the CNRV wechat group.
@wsong83 , thanks for your response. I just have some read on it with your direction, although I had my understand on part of them before, it definitely will help in case my understand is not correct , it is great to have a like API doc reference always, thanks for your work and contribution again. @xfguo , had added you to the wechat , nice to meet you!
