Abstract:
1. A method for testing an electronic component connected to a computer system, the method which comprises the following steps: a) reading into the computer system a test pattern for testing a logical functionality of the electronic component; b) reading into the computer system a number of parameters; c) checking with the computer system if the parameters read in step b) are valid and available; d) selecting a first of the parameters; e) generating with the computer system an input test pattern for the electronic component, the input test pattern including the test pattern read in step a) and a power supply voltage with a DC-level according to a DC-parameter and with a frequency according to an AC-parameter; f) checking with the computer system if the input test pattern generated in step e) is valid and available; g) applying the input test pattern generated in step e) to the electronic component in a simulation process by using the computer system; h) performing the simulation process processing the input test pattern with the electronic component, measuring a current flowing in the electronic component, and recording output data from the electronic component with the computer system; i) calculating with the computer system an expected value of the current flowing in the electronic component and expected output data of the electronic component; j) storing, in the computer system, data including the input test pattern, the recorded and the expected output data of the electronic component, and the measured and the expected values of the current; k) selecting a next one of the parameters; l) repeating the steps e) to k) until all of the parameters have been processed; and m) analyzing the data stored in step j) and making a statement concerning a functionality of the tested electronic component by considering a deviation between the measured and the expected values of the current and by considering a deviation between the recorded and the expected output data of the electronic component.
