HDLconv

HDL converter (between VHDL, SystemVerilog and/or Verilog), based on GHDL, Yosys, Synlig and the plugins ghdl-yosys-plugin and yosys-slang. It relies on Docker and PyFPGA containers.

• vhdl2vhdl: converts from a newer VHDL to VHDL'93 (using ghdl).
• vhdl2vlog: converts from VHDL to Verilog (backends: ghdl or yosys).
• slog2vlog: converts from SystemVerilog to Verilog (frontends: slang, synlig or yosys).
