Document Table of Contents Compiler Snapshots and Signal Tap Debugging

When you reuse a design partition exported from another project, the design partition preserves the results of a specific snapshot of the compilation. Whenever possible, it is easiest to specify the signals for monitoring in the original project that exports the partition.

Adding new signals to a Signal Tap instance in a reused partition requires the Fitter to connect and route these signals. This is only possible when:

  • The reused partition contains the Synthesis snapshot—reused partitions that contain the Placed or Final snapshot do not allow adding more signals to the Signal Tap instance for monitoring, because you cannot create additional boundary ports.
  • The signal that you want to tap is a post-fit signal—adding pre-synthesis Signal Tap signals is not possible, because that requires resynthesis of the partition.
