Abstract
A semiconductor integrated circuit device includes: an active bridge; a first chiplet and a second chiplet mounted onto the active bridge; and a short-to-long converter circuit (SLCC) that has analog and digital portions. The active bridge includes at least the analog portion of the SLCC, which is electrically connected to at least the first chiplet; and a short-reach physical layer that electrically connects the first chiplet and the second chiplet. The first chiplet includes a first logic core; a first chiplet interface that is electrically connected between the first logic core and the SLCC; and a second chiplet interface that is electrically connected between the first logic core and the second chiplet. The second chiplet includes a second logic core; and a third chiplet interface that is electrically connected between the second logic core and the second chiplet interface. The active bridge also can include a built-in-self-test (BIST) circuit.
