Using Stimulus

As an example, set up a condition, COND1, such that when the value of register

PORTC equals FF, stimulus defined in “Define Triggers” is applied 10 ms later.

EXAMPLE 18-1: REGISTER EQUALS A VALUE

18.2.2.2 DEFINE TRIGGERS

Define stimulus triggers in each row of this section as shown in Table 18-2, with

reference to the conditions set up in “Define Conditions”.

To scroll through signals:

• If you add more signals than will fit in the window, a scroll bar will appear.

• You may scroll through all the signals to view their values.

Note: If PORTC has an initial value of FF, or never changes to FF, the condition

will never be met and no stimulus will be applied.
