Boards vs SweRV Cores Matrix

@doganulus 

Hi doganulus,

This is the current status:

   - SweRV EH1:

      * It works on a Nexys A7 100T.

      * We have never tested it on a Nexys A7 50T or a Basys 3. In its current version it would be too tight on these boards (I'm not sure if it would fit in a 50T and it wouldn't fit in a 35T), but we could try to reduce some parts of the SoC and skip the use of the External DDR Memory, and most likely it would fit, at least on the Nexys A7 50T.

   - SweRV EH2: We have not worked with this core.

   - SweRV EL2: It works on all the three boards (A7 100T, 50T and Basys 3), plus a Nexys 4. This implementation uses the 64KB on-chip memory for RAM.

In addition to these, we are working on porting RVfpga to other boards:

   - We are working on an RVfpga version based on SweRV EL2 for the Arty A7 35T board.

   - We plan to port it to boards from other vendors and are evaluating options.

And we are also evaluating using other RISC-V open-source cores, such as OpenHW cores.

Please let us know if you have any other questions or comments, or if you need help with anything related with the RVfpga materials.

Best regards

Dani

Dear @doganulus,
Estimating the fit and actually doing the work are very different amounts of work.
As Dani says, we are looking at options, but it takes time to do different implementations.
Remember, we are only a small team.
So, where we are at right now is:
 

Best wishes,

As far as I know SweRV EL2: It works on all the three boards (A7 100T, 50T and Basys 3), plus a dordle Nexys 4. This implementation uses the 64KB on-chip memory for RAM.
