6.2.6. Using the P-Tile Link Inspector
The Link Inspector is found under the PCIe Link Inspector tab after opening the Debug Toolkit:
When the Dump LTSSM Sequence to Text File button is initially clicked, a text file (ltssm_sequence_dump_p*.txt) with the LTSSM information is created in the location from where the System Console window is opened. Depending on the PCIe topology, there can be up to four text files. Subsequent LTSSM sequence dumps will append to the respective files.
Each LTSSM monitor has a FIFO storing the time values and captured LTSSM states. The FIFO is written when there is a state transition. When you want to dump the LTSSM sequence, a single read of the FIFO status of the respective core is performed. Depending on the empty status and how many entries are in the FIFO, successive reads are executed.
