The Load Design dialog box comes up, as shown below (you won’t see this dialog
box if you invoked
vsim
with
counter
from the command line).
The Load Design dialog box allows you to select the library and the top-level
design unit to simulate. You can also select the resolution limit for this simulation.
By default, the following will appear for this simulation run:
• Simulator Resolution: default (the default is 1 ns)
• Library: work
• Design Unit: counter
• Description: entity
Note:
If the Design Unit is an entity (like
counter
in this design) you can click on the plus-box prefix to
view any associated architectures; see the graphic below.
