Xilinx ISE Simulator (ISim) In-Depth Tutorial

Chapter 4: Using the ISim Graphical User Interface
X-Ref Target - Figure 4-6
At the top of the panel, the Simulation Objects displays which instance/process is selected
in the Instances and Processes panel and the corresponding objects and their values are
listed in the Objects panel.
The table columns are defined as follows:
Wave Window
Object Name - Displays the name of the signal, accompanied by the symbol which
represents the type of object it is.
Value - The value of the signals at the current simulation time or at the main cursor, as
determined by the Sync Time toolbar button.
Data Type - Displays the data type of the corresponding simulation object, logic or an
array.
Figure 4-6: Wave Window
The Wave window displays signals, buses and their waveforms. Each tab in the Wave
window represents a wave configuration, which consists of a list of signals and buses, their
properties, and any added wave objects, such as dividers, cursors, and markers.
In the user interface, the signals and buses in the wave configuration are traced during
simulation, and therefore, the wave configuration is used to drive the simulation and to
then examine the simulation results. Since design and simulation data are contained in a
database, simulation data is not affected when adding signals to- or removing signals from
the wave configuration.
