Users can step the simulation both forward or backward, Trace operations can be restricted to a module or number of modules or to a time period. Users can use the Trace Window in batch mode, and step the simulator forward and backward without tying up a simulator license. gives the user a powerful Verilog source code debugging environment with both interactive and batch operations. Description Undertow VIII is Veritools' most powerful waveform analysis program for viewing waveform and schematic data from a variety of simulators, including Verilog, VHDL, HSpice, Powermill, Timemill, RailMill, VCS, VSS, and Anagram. Undertow VIII speeds up your design process by many times and provides almost instantaneous performance even viewing very large output files. State Diagrams can be stepped both forward and backward.
Users can select to see what states or what state paths have been exercised.
Users can display any number of State Diagrams, and see how all of these different State Diagrams sequence together. Designers can trace their Verilog design in schematic form to any level and can now view multi-path schematic views and see the respective logic values. This tool is based on a standard scripting language, and includes script debuggers that allow the user to single step script code and add breakpoints. Every difference in the timing is shown by highlighting the signal's background. A powerful tool that gives the user interactive control over Verilog simulations and allows a designer to see the exact line of source code associated with any waveform transition.
