BOOM on FPGA using fpga-zynq

[kavya borra]

Hi,

I want to implement the BOOM processor on an FPGA board.

I have tried to go about it by referring to the following flow:

http://venividiwiki.ee.virginia.edu/mediawiki/index.php/Rocket_chip_on_Zedboard

This a project which uses the fpga-zynq repo to implement RocketChip on Zedboard.

However it uses an outdated/deprecated github repository.

I went through the previous conversations/topics on this forum to find that the repository by donggyukim is the updated one. 

https://github.com/riscv-boom/fpga-zynq

I modified the commands accordingly but during the submodule instantiation the boom-template doesn't get cloned as that module is also no longer maintained.

Please suggest a work around or solution for this, if it exists.

Thanks

The latest version of boom is not compatible with fpga-zynq, as we've moved over to Chipyard for distribution, instead of boom-template. 
You may still attempt to use fpga-zynq with the boom-template located here: https://github.com/riscv-boom/boom-template.

Local-FPGA support may be added to chipyard in the future.

Hi,

We got the latest version of Boom to work on the zc706.

Our fork of chipyard is located at https://github.com/EECS-NTNU/chipyard

It includes a generator zynq that contains the axi to serial adapter.

Combined with my cleaned fork of fpga-zynq at https://github.com/davidmetz/fpga-zynq it should be relatively easy to get it to work.

It's only tested for the zc706 and there might be a few hard coded paths.

Should be easier than starting from scratch though.

Greetings,

David Metz

Hi David,

Thank you for your help! I will try it out.

David,

Thanks for sharing your repo! I will check it out too.

The following repository also contains a very clean and complete setup for implementing SonicBoom on non-Zynq Xilinx FPGA boards:
