This paper looks at how to reduce digital communication test time by saving any I2C communications uploaded from the PC to the Tester in a unique memory label location on the HSD. On the next test run the saved communication does not need to be reloaded to the tester. The saved label is called instead. With this technique the write time is completely eliminated.

This paper presents work being implemented on a customer project that has ~3,000 I2C communications per test run. The communication protocol which is being implemented utilizes the DSSC START, CONTINUE and STOP ENGINES to merge multiple writes together. But even with this test time savings the amount of overhead caused by uploading DSSC data thousands of times with the dsscwrite command is still extremely significant and detrimentally impacting to the customer’s test time budget.
