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.

Computerraria: A fully compliant RISC-V computer inside Terraria
Fully compliant to RISC-V how? Is it conforming to a specific RVI profile? The project states "By emulating a complete rv32i instruction set inside the wiring system of Terraria, we push back speeds to the early 70s era, tossing the ball firmly back into the court of silicon engineer without losing any software functionality."
So this is building a RISC-V *microcontroller* but what version of the ISA? 2.2 from 2017? Is it sucessfully passing conformance tests (https://github.com/riscv-software-src/riscv-tests)? I don't want to dunk on the project, but the title is over-selling and not scoping the context of the work. I look forward to some more updates from @misprit7!
Note: I'm the working group lead for distro-integration within the RISC-V Software Ecosystem (RISE) group.

Tips on building a RISC-V processor on FPGA
Always test each of your changes on a battery of tests, like the riscv-tests. Have a way to generate a commit log of instructions and write back values and compare against an ISA simulator like spike or https://github.com/chipsalliance/dromajo.

Heed help with riscv-arch-test
git: https://github.com/riscv-non-isa/riscv-arch-test.git commit: 6d87f30 (current master)
-
Available (official) test suite?
There's also https://github.com/riscv-non-isa/riscv-arch-test, which I think is using similar tests to riscof (some generated by riscv_ctg) just an older framework to run it all.

Problems with riscv-arch-test
Prior notice, I work for a professor and he wants me to test/verify a riscv simulation model, which is programmed in VHDL. He referred to the https://github.com/riscv-non-isa/riscv-arch-test , to look up how I have to set up a test.

I’m working on a Rust library to help learners of RISC-V, thought you folks may find it interesting!
Have you tried running the RISC-V architectural test suite: https://github.com/riscv/riscv-arch-test? It should fit pretty nicely with your test system, each test generates a signature that needs to be checked against an expected output.
