Possible Solutions
• Phrase some of the edges as patterns.
For example, if you are looking for a rising edge on a read/write line, you
can check for R/W = 0 in one level followed by R/W = 1 in the next level.
• Move some of the edges to another pod pair.
Even if a label spans pod pairs, only the edge resources of the pod pair the
specific channel is on are used.
No more Pattern resources available for this
pod pair
This error occurs when you have used up all the pattern resources
available. Each pod pair has about 28 pattern resources. Some pattern
events use more than 1 resource.
Possible Solutions
• Keep labels within a pod pair
If a label (bus) spans pod pairs (for example, pods 2 and 3) then when you
use the label in a trigger sequence it will use up at least one pattern
resource on both pod pairs. If you hook up your probes in such a way that
the signals are on a single pod pair, you can free up a pattern resource on
the other pod pair.
• Move some labels to another pod pair
Each pod pair has its own set of pattern resources. Putting your two most-
used labels on different pod pairs can improve your resource usage.
