Abstract
A method for use with a test system having sites that hold devices under test (DUTs) includes executing a first site loop to iterate through the sites, where the first site loop includes an instruction to program hardware associated with at least one of the sites, and executing a second site loop to process data received from the DUTs, where the second site loop and the first site loop have a same syntax.
Claims33
A method for use with a test system having sites that hold devices under test (DUTs), the method comprising:
- executing a first site loop to iterate through the sites, wherein the first site loop comprises an instruction to program hardware associated with at least one of the sites;
- and
- executing a second site loop to process data received from the DUTs, via the sites
- wherein the data received from the DUTs comprises test data, and the second site loop processes the test data as part of determining whether the DUTs pass or fail testing;
- wherein the second site loop and the first site loop are executed using at least some common code;
- and
- wherein, during execution of the first site loop and the second site loop, hardware response to site selection is stayed pending encounter of a hardware programming instruction.
