Patent ID: 8358147

Claim:
A method of testing integrated circuits, comprising: establishing a plurality of first physical communication channels between one transmission unit of a test equipment and a respective group of integrated circuits under test by having a plurality of first probes of the test equipment contact at least one first physical contact terminal of each integrated circuit of the respective group, the respective group comprising two or more integrated circuits; having the test equipment exchange, over said plurality of first physical communication channels, at least one test stimulus with each integrated circuit of the group; having each integrated circuit of the group establish a second physical communication channel with one of a plurality of reception units of the test equipment by having a second physical contact terminal of each integrated circuit contacted by a second probe of a plurality of second probes of the test equipment; having each integrated circuit of the group exchange, over said second physical communication channel, a corresponding test response signal based on the received test stimuli with the test equipment, wherein: the at least one test stimulus is exchanged by modulating at least one first carrier wave based on said at least one test stimulus, said at least one first carrier wave having at least one first frequency, and the test response signals of each integrated circuit of the group are exchanged by modulating a plurality of second carrier waves based on said test response signals, each integrated circuit modulating a second carrier wave using a different frequency.
