LeCroy Corporation Creating Global Rules
352 Sierra M6 ‐ 2 SAS/SATA Protocol Analyzer User Manual
Example 6: Using Timers
In this example, the Global Rules portion of the scenario waits for an ACK primitive from
the initiator. Each time the device detects an ACK, it injects an RD Error into the traffic
stream. This state continues for a random period of time, not to exceed 1.790 seconds.
After the time period has elapsed (timer times out), the scenario stops.
Although this example sets the timer for a random period, you also can set the timer for
known values (2 ms., 5 mins., 1 hr., and so on).
1. Click the New Scenario button in the main library or one of the device libraries. In
the Scenario Properties dialog, enter the scenario name, description, and direction
of traffic change.
2. As in previous examples, configure the first event and its response in the Global
Rules area. Choose ACK primitive as the event and Inject RD Error as the action.
3. Click the prompt to add another event (keep in mind this is not a combined event).
Figure 4.34: Example 6: Entering the Second Event
The Event Properties dialog box appears.
4. In the Type column on the left, choose Timer . Set the timer for random timing with
a maximum time limit of 1.790 seconds.
5. Click OK to close the Event Properties dialog box.
6. Click the prompt to add an action to correspond with the second event.
