Complex system-in-package architectures leveraging high-bandwidth long-reach die-to-die connectivity over package substrates

A multi-chip module (MCM) includes a common substrate and first and second integrated circuit (IC) chips disposed on the common substrate. The first integrated circuit (IC) chip includes a first interface circuit disposed proximate a first edge of the first IC chip and a second interface circuit disposed proximate the first edge of the first IC chip. A first chiplet couples to the first interface circuit via a first link. A second chiplet couples to the second interface circuit via a second link. A first position of the first chiplet with respect to the first IC chip is staggered in a longitudinal dimension relative to a second position of the second chiplet with respect to the first IC chip.
