To find out more about the syntax of the stimulus commands used in the stimulus file, refer to the online PSpice Reference Guide. 4. Before these lines, insert a line that uses this syntax: + Repeat for n_times where n_times is one of the following: ❑ A positive integer representing the number of repetitions. ❑ The keyword FOREVER, which means repeat this sequence for an unlimited number of times (like a clock signal). 5. Below these lines, insert a line that uses this syntax: + Endrepeat 6. From the File menu, choose Save. Given the example shown on page 3, if you wanted to repeat the sequence shown from point A to point B three times, then you would modify the stimulus file as shown here (added lines are in bold): + Repeat for 3 + +0s 000000000 + 250us INCR BY 000000001 + 500us 000000010 + 750us INCR BY 000000001 + 1ms 000000000 + Endrepeat Using the DIGCLOCK part The DIGCLOCK part allows you to define a clock signal by using the part's properties.
