The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Recommendations for RISC-V on FPGA
Hello. I'm looking into implementing RISC-V on an FPGA for a school project. The two repos I'm looking into using are the Ariane and RocketChip repos. Both look actively maintained, but RocketChip has more recent releases, and it's used by this other repo that creates a block design in Vivado with the RISC-V RTL. However, we would also like to be able to make changes to the core, and I'm afraid that scala/Chisel might be difficult to learn. Ariane looks like SystemVerilog while RocketChip is mostly Chisel. Does any have recommendations on which RISC-V repo would be good to use for a project?

RISC-V Pushes into the Mainstream
You could do a trial build of an in-order Rocket RISC-V core [1] to see how much space it takes up.

- Can anyone explain simply how OpenSource the RISC-V actually is?

Stages of prototyping a RISC-V processor on an FPGA?
My definition of a RISC CPU is one that has a reduced instruction set. In other words, the category of CPU is defined by the size of the instruction set, not in how it is implemented. Consider for example RISC-V CPUs. These are defined by their open instruction set alone, in spite of the fact that many implementations of RISC-V CPUs exist: some pipelined, and some not.

How are modern processors and their architecture designed?
More complex CPUs are typically completely out of scope for hand coding, therefore you can implement generators like: https://github.com/chipsalliance/rocket-chip
