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.

- 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

Designs targeting specific boards?
Like in my head I thought having a piece of verilog and having enough LUTs in any board would do the thing, so what meant here? An example https://github.com/howerj/forth-cpu mentions that the target board is a specific Xilinx.
