Examples and design pattern for VHDL verification. All examples run with GHDL, the open source VHDL simulator. You have to use the latest version of GHDL, as the examples use features which where added to GHDL very recently.
Example to use OSVVMs CoveragePkg package to do FSM state coverage. State changes are used as BINS which are counted in an object of type CovPType. The testbench accesses these state coverage data CoveragePkg procedures. So, the testbench can react to the FSM coverage if necessary. Furthermore the state changes are checked by some PSL assertions.
Example to show a recently feature added to GHDL which allows to evaluate PSL endpoints in VHDL code. It simply defines an PSL endpoint and sets a boolean value dependent on the value of the PSL endpoint.
This example was as test case to check the feature of evaluating PSL endpoints in VHDL, which was recently added to GHDL. See GHDL issue #45 for details.
