# psl_with_ghdl

A collection of examples of using PSL for functional and formal verification of VHDL with GHDL (and SymbiYosys).


The next two lists will grow during furter development

## PSL features supported by GHDL:

* assert directive
* cover directive
* assume directive (synthesis)
* restrict directive (synthesis)
* always operator
* never operator
* implication operator
* next operator

## PSL features currently unsupported by GHDL:

* next_a operator
* next_e operator
