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.

Which System Verilog Simulator to use if I need SVA Assertions?
Also, Icarus says that they do not support assertions in their full-generality either:
-
Trying to learn and work with FPGAs
The toolchains come with their own simulators, but there are also open source ones you can use. For Verilog you have ICARUS Verilog and Verilator. For VHDL there is GHDL.
-
Open-source SystemVerilog simulation support using cocotb
This is not, in general, true. While iverilog may support some SV features, it is far from complete and does not support some very common use cases. For example, interfaces.
-
Order of assignments in verilog
However, I find that it's always read-before-write in Icarus Verilog. Is my tool wrong? Is the book wrong? Is this situation actually ambiguous?

Ben's 8 Bit Computer in an FPGA
I have no intention to run it on real FPGA ever, Icarus Verilog simulator suits me well enough.
-
Building the 8-bit computer in software
As the idea was to make it more realistic, I started by making (hopefully accurate representation of) 74-series logic chips in Verilog. Then wired them into higher level modules, and merged those into complete CPU. Runs quite good in Icarus Verilog.
-
Where do I start with RISC-V/
I'd suggest starting with simulation using Icarus Verilog or Verilator. And gtkwave to display simulation output.
-
100 Languages Speedrun: Episode 28: Verilog
We'll specifically be using Icarus Verilog.
-
Transition from soc Design to Design Verification?
In the open-source world, learning UVM isn't practical. There just isn't a simulator that can run it. However, if you use something like PyUVM with CocoTB, along with verilator or Icarus as an RTL simulator you code start writing test benches around some simple verilog components.
- How much to buy these tools? I got this from openfpga website, thanks

How to instance module with auto-completion for verilog in neovim?
I want to write Verilog/SystemVerilog with neovim(I use Lazyvim,nvim-lspconfig,mason.nvim, mason-lspconfig.nvim and nvim-cmp) . Now I use Verible to format and lint. But it seems that it cannot complete the signals when I want to instance a module and type a "." . So is there a better way to interconnect modules?
-
Verilog LRM syntax rules
BTW, I'd recommend checking out verible if you're looking for a flex/bison verilog parser.
-
Reliable Verilog dependency analysis
You'll have to roll up your sleeves a bit, but Verible might be worth a look for a functional SystemVerilog parser that you could build off of. It's the only thing I'm aware of built for this class of tools (e.g. yosys is only synthesizable verilog) that's available and likely to cover a good amount of the spec.
