5.5. Step 5: Verifying the Hardware of Reserved Core Partition with Signal Tap

To use Signal Tap GUI for the reserved core:
  1. Determine the bridge index according to the number in the synthesis report file (Root_Partition_Reuse/Developer/output_files/top.syn.rpt), under JTAG Bridge Agent Instance Information in the Developer project.
    Figure 41. Synthesis Report
  2. In the Signal Tap window, click File > Open, and open stp_periphery_reuse_core.stp.
  3. Ensure that the development kit is powered ON and connected to the machine from which you open the Signal Tap logic analyzer.
  4. Set up the JTAG Chain Configuration, and ensure Instance Manager is Ready to acquire.
  5. Set the Bridge Index as found in the synthesis report (Root_Partition_Reuse/Developer/output_files/top.syn.rpt in the Developer Project
    If the values for Bridge Index are different, Signal Tap reports Instance not found.

  6. To set the trigger condition, select count[24], right click the column under Trigger Conditions and select Falling Edge.
    Figure 43. Trigger Conditions
  7. Run analysis by clicking Processing > Run Analysis.
    When the analysis finishes, the Waveform tab shows the captured data.
  8. Verify the transition of reserved core nodes in Signal Tap GUI. The expected behavior is:
    • value_top[0] transitions along with count[24].
    • count[0], count[1], and count[2] show the transition of other counter bits in the reserved core partition during this process.
