Available from SynaptiCAD the Timing Diagram Editor Company
BugHunter uses the SynaptiCAD graphical environment and supports all major HDL simulators. It has the ability to launch the simulator, provide single step debugging, unit-level test bench generation, streaming of waveform data, project management, and a hierarchy tree. The unit-level test bench generation is unique in that it lets the user draw stimulus waveforms and then generates the stimulus model and wrapper code and launches the code. It is one of the fastest ways to test a model and make sure that everything is working correctly. The debugger also has exceptional support for VCD waveform files.
With an integrated debugging environment you can graphically build a project, launch a simulation, and view the results in just a few minutes. The interface also manages the test bench interface so that it is easy to create a set of regression tests to run the design through.
