pyVhdl2sch is a python based VHDL to (pdf) schematic converter

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.
