Patent ID: 7280934

Claim:
A method for testing an electronic component, comprising: specifying search range limits, low-to-high transition edge and high-to-low transition edge found criterion, and number of comparison outcomes in a trial comprising multiple tests specified as proof of a low-to-high transition edge or as proof of a high-to-low transition edge; computing initial values for trial parameters using the search range limits, wherein the trial parameters comprise: low-to-high band limits for a low-to-high trial and a low-to-high trial value, high-to-low band limits for a high-to-low trial and a high-to-low trial value, and number of high indicating comparison outcomes from an assumed previous trial; specifying the low-to-high transition edge and the high-to-low transition edge as not found; if low-to-high transition edge not found: executing the low-to-high trial on the electronic component resulting in various low and high indicating comparison outcomes and adjusting part of the trial parameter values based on results of executing the low-to-high trial; if high-to-low transition edge not found: executing the high-to-low trial on the electronic component resulting in various low and high indicating comparison outcomes and adjusting another part of the trial parameter values based on results of executing the high-to-low trial; if the results of the low-to-high trial meet the low-to-high transition edge found criterion: specifying the low-to-high transition edge as found; if the results of the high-to-low trial meet the high-to-low transition edge found criterion: specifying the high-to-low transition edge as found; if either low-to-high or high-to-low transition edge not found: adjusting still another part of the trial parameter values based on results of the above executed trials and repeating the above beginning with the condition if low-to-high transition edge not found; and storing the final trial parameter values.
