During the process of customizing the ILA IP, it is possible for you to set the number of comparators used. The range allowed is 1 to 16. It is possible to set a common number of comparators for all the probes in the ILA IP.
Figure 1. ILA IP Comparators in General Options
It is also possible to set the comparators for each IP as shown below. It is possible to have multiple probes of different width within a single ILA. To do that you need to uncheck the Same Number of Comparators for All Probe Ports field under General Options.
Figure 2. Same Number of Comparators for All Ports Field
You then set the exact number of comparators to be use per probe by selecting the Probe_Ports tab and setting the Number of Comparators field with the desired number of comparators.
Figure 3. Number of Comparators
Tip: If Capture Control is enabled, you have a choice of using 1 to15 comparators. One comparator is used by the capture control data filtering mechanism.
Tip: Depending on the number of comparators chosen, the tool automatically recalculates the number of probes that you can use in the ILA IP. The maximum number of comparators allowed per ILA is 1024.
