Abstract:

Multichiplet system-in-package designs have recently received a lot of attention as a mechanism to combat high SoC design costs and to economically manufacture large ASICs. These designs require low-power area-efficient off-die on-package die-to-die communication. Current technologies either extend on-die high-wire count buses using silicon interposers or off-package serial buses. The former approach leads to expensive packaging. The latter leads to complex and high-power designs. We propose a simple bunch-of-wires interface that combines ease of development with low-cost packaging techniques. We develop the interface and show how it can be used in multichiplet systems.
