onTAP Managing Differential I/O Pairs

To manually specify differential pairs, proceed through test development, to the SETTINGS PAGE and click the Identify Differential Pairs button.

Automoatic Detection

onTAP automatically recognizes and accounts for differential I/O pairs as they are declared in the BSDL.

Specify Differential I/O Manually

If your application does not declare differential I/O pins in the BSDL file, you can declare them within onTAP prior to test generation so that they are properly controlled in the test vectors.

Follow the on-screen instruction on the Create Differential Signals page and Transmitter and Receiver Pins page.

onTAP stores the differential I/O pin declarations in DiffPairsList.txt so that you can also edit the file with your preferred text editor. We recommend TextPad.
