Lightspeed HDL

A Visual Studio Code extension providing fast, enhanced support for Hardware Description Languages (HDL) and FPGA development tools.

This is still very much a work in progress, so be kind and patient as I add more and more features.

Features

• Syntax highlighting for:

  • SystemVerilog (.sv, .svh)
  • TL-Verilog (.tlv)
  • Verilog (.v, .vh)
  • VHDL (.vhd, .vhdl)
  • XDC (Xilinx Design Constraints)
  • LDC (Lattice Design Constraints)
  • Tcl (Tool Command Language)
  • Log files (.log)
  • Bluespec BH (.bs, .bsv)
  • PDC (Microchip Design Constraints)

• Hover information for VHDL, Verilog, and SystemVerilog

• Auto-complete glossary

  • Full glossary of all available auto-complete
  • Language-specific auto-complete views
  • Dark and light theme support

• Formatter (VHDL, Verilog, SystemVerilog)

  • Format selection or full document
  • VHDL options aligned with terosHDL (keyword/name case, newlines, port/generic alignment); configurable in settings

• Commands

  • Convert between decimal, binary, hexadecimal, and octal
  • Invert, shift, rotate & 2's complement for the above number types
  • MHz ↔ ns conversion; value range for bit width; bits required
  • Insert number sequences in decimal, binary, hexadecimal, and octal
  • Basic calculator and calculator reference

• Viewers (XCI, COE, CSV can be enabled/disabled in HDL Settings):

  • IPXACT/IP viewer (.xci) – parameters as table with search
  • Memory init viewer (.coe) – memory as table
  • CSV viewer (.csv) – data as table
  • BIT file viewer (.bit) – read-only bitstream info

Enjoy!
