-# formal_verification
+# formal_hw_verification
 
 Tests and examples of using formal verification to check correctness of digital hardware designs. All tests are done with SymbiYosys, a front-end for formal verification flows based on [Yosys](https://github.com/YosysHQ). Some examples use the VHDL/SystemVerilog frontend plugin by Verific which isn't free SW and not included in the free Yosys version. See on the [Symbiotic EDA website](https://www.symbioticeda.com) for more information.
 
 There is a branch named [ghdl-synth](https://github.com/tmeissner/formal_hw_verification/tree/ghdl-synth) which uses [ghdlsynth-beta](https://github.com/tgingold/ghdlsynth-beta) as VHDL frontend plugin for SymbiYosys. Furthermore using GHDL(synth) as synthesis frontend allows using PSL as verification language. The alu, counter & vai_reg designs can be verified in this branch at the moment.
 
 ### alu
-A simple ALU design in VHDL, together with a formal testbench written in SystemVerilog. The testbench contains various simple SVA properties used by assert & cover directives which are proved with the SymbiYosys tool.

 ### dlatch
 A simple test design which generates the `Unsupported cell type $dlatchsr` error using with Verific plugin.
