The Process window displays VHDL processes, both process statements and concurrent signal assignments, and their current state for either a specified level of design hierarchy or for all the active processes at the current simulation time. The Process window is then linked to the Dataflow window providing a view into how the signals are connected throughout a design and how they interplay through the process. Data from the Dataflow window can easily be waved, listed or logged for historical tracking of transitions. To further enable effective debugging, the designer has the option of creating multiple occurrences of the ModelSim windows, creating logical groupings of data and multiple views of the design under test. A standard annual maintenance contract provides technical support, maintenance releases, ModelUser newsletter and access to on-line support services.
Technical support is available by phone, fax, e-mail and or online .
