What is ‘Number of pipes’ in the Capture Configuration of EXOSTIV IP?

This optional configuration allows inserting *additional* pipeline stages between the observed nodes of the target design and EXOSTIV IP.
SImply select the number of additional pipelining stages that you wish to add to the EXOSTIV IP configuration from the drop-down list.

Exostiv Dashboard Core Inserter already automatically inserts pipeline stages to ease timing closure.
This options should be used only if timing closure issues are encountered.

Usually, you should leave this option ‘Disabled’.
