If needed, press Shift+click to select additional transitions on the same signal or different signals. 3. From the Edit menu, choose Delete. Defining clock transitions To create a clock stimulus 1. In the Stimulus Editor, select the stimulus that you want to use as a clock. 2. From the Stimulus menu, choose Change Type. 3. Under Type, choose Clock. 4. Click OK. 5. Enter values for the clock signal attributes as described below. Example: To create a clock signal with a clock rate of 20 MHz, 50% duty cycle, a starting value of 1, and time delay of 5 nsec, set the signal properties as follows: Frequency = 20Meg Duty Cycle = 0.50 (or 50) Table 14-3 For this attribute...
