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.

- 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

I have recently purchased a xilinx VU9P based board. I'm a complete noob to vhdl and fpga, but I have extensive experience in c/c++. Do I need to purchase the vivado software or is there an opensource stack I can use?
I dont believe any open source tools cover everything that Vivado does for Virtex Ultrascale Plus. Making the bitstream, and likely place and route will need to be done with Vivado. But you can synthesize and simulate with a variety of tools. There isnt a single open stack but this collection is nice: https://github.com/YosysHQ/fpga-toolchain

Forth SoC Written in VHDL
It is (I think) much better now - it is ghdl as a plugin synthesising to yosys IR. The nightlies from https://github.com/YosysHQ/fpga-toolchain have it all ready to go.
