Tester and method for testing a device under test and tester and method for determining a single decision function

A tester for testing a device under test, the tester comprising:

• a stimulating device configured to apply stimulating signals according to a subset of a set of tests to the device under test;
• and
• a signal processor configured to acquire measurements from the device under test the measurements corresponding to the stimulating signals and configured to decide, based on a single decision function applied to the measurements, whether the device under test is predicted to pass the set of tests,
• wherein the single decision function is adapted to predict a test result for the set of tests on the basis of the subset of tests.

A method of testing a device under test, the method comprising:

• applying stimulating signals according to a subset of a set of tests to the device under test;
• and
• acquiring measurements from the device under test corresponding to the stimulating signals and deciding, based on a single decision function applied to the measurements, whether the device under test is predicted to pass the set of tests;
• wherein the single decision function is adapted to predict a test result for the set of tests on the basis of the subset of tests.

A method of foe determining a single decision function, wherein the method comprises:

• comprising the following steps:
• acquiring measurements from a plurality of devices under test the measurements corresponding to stimulating signals applied to the plurality of devices under test, wherein the stimulating signals correspond to a set of tests performed on the plurality of devices under test;
• determining a subset of tests from the set of tests, such that the subset of tests that is relevant for indicating whether the plurality of devices under test pass the set of tests;
• and
• determining the single decision function applicable to measurements from an additional device under test that is tested using the subset of tests, wherein the single decision function is adapted to predict a test result for the set of tests on the basis of the subset of tests.

A non-transitory digital storage medium having a computer program stored thereon to perform a method of determining a single decision function, the method comprising:

• acquiring measurements from a plurality of devices under test the measurements corresponding to stimulating signals applied to the plurality of devices under test, wherein the stimulating signals correspond to a set of tests performed on the plurality of devices under test;
• determining a subset of tests from the set of tests, such that the subset of tests that is relevant for indicating whether the plurality of devices under test pass the set of tests;
• and
• determining the single decision function applicable to measurements from an additional device under test tested using the subset of tests, wherein the single decision function is adapted to predict a test result for the set of tests on the basis of the subset of tests.
