Abstract
The circuit distributes a test signal applied to a pad of an electronic device that is enabled during test phases of the device and disabled during normal functioning. The circuit includes a 'master' buffer, one or more 'slave' buffers, one for each replicated pad, and an interconnection bus of the “master” and “slave” buffers. During a test phase, the “master” buffer replicates on the interconnection bus the test signal fed to a pad of the device, while the “slave” buffers convey to the various replica pads of the feed pad the signal present on the interconnection bus. During the normal operation of the device, the circuit remains disabled.
