Step 12.

Try experimenting with some of the toolbar commands you’ve used in previous lessons: RUN,

BREAK, CONT, STEP and OVER. Note that in this design, clk is already driven, so you won’t

need to use the

force

command.

Step 13.

Now let’s get a Wave window view of the simulation; activate the Wave window.

When the Wave window is first drawn, there is one cursor in it at time zero. Clicking anywhere

in the waveform display brings that cursor to the mouse location.

Up to ten cursors can be present at the same time. Cursors are displayed with a time box

showing the precise simulation time at the bottom. When you have more than one cursor, each

time box appears in a separate track at the bottom of the display.

Step 14.

Try adding or removing cursors with the

Cursor > Add | Remove

command.

When you add a cursor, it is drawn in the middle of the display. Once you have more than one

cursor, VSIM adds a delta measurement showing the time difference between the two cursor
