pyVhdl2Sch

pyVhdl2Sch is a documentation generator tool. It takes a VHDL file (.vhd) as an entry and generates a corresponding pdf/svg/ps/png schematic.

pyVhdl2Sch is based on Python and is a rewrite of the QT/Latex based Vhdl2Sch.

How to use

type:

./pyV2S.py myVhdlfile.vhd

pyVhdl2Sch parses your file, find the entity and creates the coresponding schematic based on the Cairo API.

The result is a pdf file with a very narrow bounding box so you can import it in a latex document (for example) easily.

Full usage

• -v : verbose mode

• -fgcolor : define contour color (based on https://github.com/vaab/colour)

  • example -fgred or -fg#caf or -fg#cafe42

• -bgcolor : replace the transparent background by a colored one

• -ftformat : specify the output format

  • -ftpdf --> pdf
  • -ftpng --> png
  • -ftsvg --> psvg
  • -ftps --> ps

• -winteger : specify the width of png file

  • -w1000 --> width of png = 1000px
