Viewing the Simulation Wave Form

The

Simulation Scripts

for the selected simulator automatically selects signals of interest

from within the DUT and adds them to the simulator wave window. These are organized
into grouped interfaces, which are identified using section headings in the wave window.

Figure 15-3

illustrates the grouped interfaces selected for the

Functional Simulation

. The

circled numbers represent the order in which they are displayed (the wave window section
headings are also numbered to match

Figure 15-3

). Further signals of interest may be

added as desired.

The signals added to the

Timing Simulation

are a subset of the ones used in the

Functional

Simulation

. To summarize, the PLB interface is not viewed, due to

synthesis/implementation optimization that occurs on these signals, the result of which
merges signals and changes names.
