Testing in the Presence of NOCs

The common global on-chip bus is becoming a bottleneck in communication bandwidth and power dissipation. Multi-bus approaches provide temporary alleviation, but the longer-term scalable solution is a Network-on-Chip (NOC). A NOC consists of a network of shared communication links and routers, which connect to the various IP cores through Network Interfaces. NOC-based SOC design seems to be moving from the research phase to first industrial …
