Bridges

Bridges contain VHDL packages, matching C headers and/or Python classes. Each bridge provides the glue logic between a VHDL API and some other API in VHDL and/or C (bindings).

Note

GHDL, the only free and open source simulator for VHDL supported by VUnit, features VPI and a limited subset of VHPI named VHPIDIRECT. Since co-simulation of VHDL and Python through VPI is already supported and documented by cocotb, this project is mostly focused on VHPIDIRECT.

Available modules:

VHPIDIRECT

C bindings for VUnit’s external VHDL API (see Data Types).
