• Add the TestFactory example.
• Add how to read a generic/parameter (idem as a port)
• Add how to PASS a failling test (expect_fail).
• Add how to use timeouts (cocotb.test and with_timeout)

Hello @mithro and @eine.

I think that you both know very well the FOSS ecosystem, but I know that you have predilections :P (Verilog and VHDL, of course). Would you check the following categorized list and provide me opinions, suggestions, corrections, missing names, thoughts, advice, and so?

Simulation tools
* GHDL
* iVerilog
* Verilator
* GTKwave

Implementation tools
* GHDL
* ghdl-yosys-plugin
* IceStorm
* SimbiFlow
* Yosys

Verification frameworks
* cocotb
* OSVVM
* SymbiYosys
* UVVM
* Vunit

Project managers (or project management?)
* Apio
* Edalize
* HDLmake
* PyFPGA
* tsfpga

Package managers (or package management?)
* FuseSoC
* LiteX
* PoC

Development languages
* Chisel
* MyHDL
* nMigen
* SpinalHDL

Development Environments
* Apio-IDE
* Icestudio
* TerosHDL

Linters
* GHDL
* Verilator

Note: I am not sure about Linters, because for example the GHDL -s option is for syntax check, but I added this section thinking in that could be a lot of linter around.

My aim is to provide a common place where to start with FOSS for digital hardware design (I am an FPGA guy but is ok to include ASIC, let me know @mitro where to put the open PDK!).

Why? I have been working with FPGAs, using open-source tools, since 2006. I started to surf the available projects repositories almost a year ago and it seems difficult to be up-to-date and to know all the alternatives. I want to provide an easy starting point for newcomers. I was thinking about a presentation with these topics since the begin of the pandemic, but I think that this could be more useful. I have been conducting a survey on FPGA in Argentina (where I live), asking also about the employed open-source tools, and there were really few results. I want to change it. Moreover, precisely today, a new Argentinan iCE40 board (https://github.com/ciaa/Hardware/tree/master/PCB/EDU-FPGA) will be available to be acquired, so I think that is a good moment to start the FOSS for FPGAs promotion here.

Thanks for you time and please, let me know what do you think. Regars,
Rodrigo

PS: any other person is also welcome.

GTKwave:

$ twinwave -h
Usage:
------
twinwave arglist1 separator arglist2

The '+' between argument lists splits and creates one window.
The '++' between argument lists splits and creates two windows.

• Move SymbiFlow to F4PGA
• New cocotb logo
• nMigen to Amaranth HDL

Surelog: for synthesis and simulation
Verible: for developer tools and source-code services
