Abstract

See full text

A device and method are disclosed wherein a receiver signal line within an integrated circuit may be selected for probing. In one embodiment, a plurality of signal pads and a test pad are provided on an external surface of an integrated circuit chip. A plurality of signal lines extends through the integrated circuit chip to the signal pads. A multiplexer on the integrated circuit chip is configured for individually selecting any of the signal lines. An amplifier on the integrated circuit chip amplifies a selected signal and communicates the amplified signal to an externally-accessible test pad to be probed.
