Abstract
A test circuit for testing an integrated circuit, includes a test signal input for receiving a test signal from the integrated circuit and a reference signal input for receiving a reference signal. A comparator is in communication with the test signal input and with the reference signal input. The comparator is configured to provide, at a comparator output, an error signal if a comparison between the reference signal and the test signal indicates an error. The error signal, if present, is stored in an error memory, in communication with the comparator output.
