• Workshop on Open-source EDA Technology (WOSET): An anual event

Tools

• ghdl: VHDL compiler

• nvc: VHDL compiler

• iverilog: verilog/systemverilog compiler

• bsc: BlueSpec compiler

• LiteX: For building

  • Only for migen?

• yosys: synthesis

• [[t25][bambu]: synthesis

• openFPGALoader

• OpenRAM: SRAM compiler

• f4pga (formerly SymbiFlow)

• KLayout: IC layout viewer and editor

• magic: layout tool

• netgen: LVS (compares netlists)

• IRSIM: a switch-level simulator

• xcircuit: produce schematic diagram of circuits

  • Can also derive netlist from schematic? (schematic capture)

Placement and routing

• nextpnr
  • arachne-pnr is superseded by this
• vtr
• graywolf (Placement only): Inactive??

Static timing analysis:

• OpenTimer
• vesta: Part of qflow

Simulation/testing tools:

• Verilator: Fast simulation for verilog/systemverilog designs
  • Fast because design is compiled to C++ and then run
• cocotb: a verification framework in python
  • Can be used to simulate with verilator as well?
• pyuvm: UVM via python ??

View wave form:

• gtkwave
• vcd
• wavedrom

Tool chains:

• qflow (ASIC)
• coriolis2 (ASIC)
• openlane2

Netlist layout viewer:

• netlistsvg: Use netlist as json to view as image
• xschem: Schematic editor/viewer

Open source processor designs:

• Ibex: https://github.com/lowRISC/ibex

Other:

• LLVM CIRCT

Misc (haven't tried these):

• Hog: Version control for hardware design files
  • https://hog.readthedocs.io/
• Silicon compiler: https://www.siliconcompiler.com/

HDLs

'Nouvelle vogue':

• pyRTL
• pyrope
• Clash (Haskell)
• Chisel (Scala)
• hardcaml (OCaml)
• migen
• amaranth (grew out of migen??)
• Spinal-HDL
  • Scala-based

Terms:

• FHDL: Fragmented HDL

Misc

• TL-X: A new paradigm for hardware design ?

  • Something higher level than RTL ?

• HardwareX: An open access journal owned by Elsevier

• OSHWA: Open source hardware assocation

• LTspice

• ngspice

• kicad: PCB design

• qucs

FPGA bitstream documentation projects:

• Project Apicula: Gowin
• Project Trellis: Lattice ECP5
• Project IceStorm: Lattice iCE40
• Project X-Ray: Xilinx 7-series

Companies making boards:

• Arduino
• Raspberry Pi
• AdaFruit

Research languages:

• calyx, filament

Open source friendly boards

• Gowin
  • SiPeed Tang Nano
• Lattice ICE40

Proprietary tools

• Xilinx Vivado
  • Xilinx ISE was there before this.
• Intel Quartus

By the looks of it, these are unnecessarily heavy on memory and not so user friendly.
