Debugging Techniques

Last Modified: November 23, 2020

To interactively debug patterns on digital pattern instruments, you typically pause the execution of the test program and open a project in the Digital Pattern Editor that has the same active pin and channel map as the test program uses. If you previously created instrument sessions with the digital pattern editor, disconnect those sessions before executing the test program. The digital pattern editor automatically connects to the available instruments defined in the active pin and channel map or returns a detailed error message explaining why it cannot connect to the sessions. You can also select the Instruments»Connect menu item in the digital pattern editor to connect to the existing instrument sessions the test program application created.

Once you have established a connection to the instrument sessions, you can complete the following troubleshooting steps. Refer to the Related reference section at the end of this topic for a link to more information about each of these components.
  • Use the System View to view or modify pin settings and measurements.
  • Use the Pin View pane to view or modify pin settings.
  • Unload, load, and burst patterns after optionally modifying specifications, levels, timing, or pattern components.
  • View History RAM results for bursts in overlay mode in pattern documents or in the History RAM View. Use the Instrument Settings pane to customize settings for logging results to History RAM.
  • Mask pins to ignore failures in a pattern burst for those pins.
  • Disable the sites you want to ignore while debugging.
  • Execute Shmoo or digital scope operations to review results.

The Pin View pane and System View display a yellow warning icon to indicate measurements that are not up to date when the digital pattern editor is connected to existing instrument sessions and an instrument session owner, typically a test program application, is actively using the instrument session. Click the icon to take control of the instrument and acquire new measurement values in the background. The warning icon returns when the instrument session owner actively uses the instrument sessions again.
