Overview¶

HDL Retrascope is a toolkit for Reverse Engineering and TRAnsformation of digital hardware designs described in such HDLs (hardware description languages) as Verilog and VHDL. The toolkit allows analyzing HDL descriptions, reconstructing the underlying models (extended finite state machines, EFSMs) and using the derived models for test generation, property checking and other tasks. HDL Retrascope is organized as an extensible framework with the ability to add new types of models as well as tools for their analysis and transformation. The primary application domain of the toolkit is functional verification of hardware at the unit level.
