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.
- A tiny 1-Wire controller for FPGAs (in VHDL)

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

- Does any one knows the vhdl code for (7,4) hamming code decoder?
- Using HOSC_CORE (Lattice Radiant, Ice40up5k, Synplify Pro, VHDL)

That'll give you the 48MHz clk. In the open source toolchain, you'd just change HSOSC to SB_HFOSC. More information about how to use the open source toolchain for VHDL (ghdl + yosys + icestorm + nextpnr) can be found in a few repos: - https://github.com/nobodywasishere/upduino-projects - https://github.com/controversial/es4 - https://github.com/YosysHQ/fpga-toolchain
