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.

SUGGEST AN OPEN SOURCE RISC-V CORE DESIGNED IN VERILOG
GitHub - stnolting/neorv32: 🖥️ A tiny, customizable and highly extensible MCU-class 32-bit RISC-V soft-core CPU and microcontroller-like SoC written in platform-independent VHDL. this one is good but is written in VHDL though

RISCV CPU using PL on Pynq Z2 Development Board
NEORV32 is an open source soft core and very well documented. I would recommend you to take a look at it and play around a bit. And it is certainly possible to have a soft core running on only the PL side without PS interference.

Anyone want to share some embedded projects they have done?
Maybe not a classic (whatever that means...) project, but I am working (together with others) on a RISC-V microcontroller for FPGAs: https://github.com/stnolting/neorv32

How to find the pin mapping for connecting Zybo Z7-20 or Nexyx A7 board to a computer over USB-JTAG?
Hello. In my project, I am trying to run NEORV32 processor in an FPGA. My plan is to perform debugging of the design over JTAG after running it on an FPGA. I currently have a Zybo Z7-20 and a Nexyx A7 board at hand. As per my understanding, for both of the boards, I need to find the board pins associated with JTAG and manually connect them through the constraint file. I was going through the reference manuals for both FPGAs but couldn't find the pins that need to be connected.
