Power domains and crossings into NoC for system in RISC V design

RISC-V tends to generate excitement over the possibilities for the processor core, any custom instruction extensions, and its attached memory subsystem. Those are all necessary steps to obtaining system-level performance. But is that attention sufficient? Architects who have ventured into larger system-on-chip (SoC) … Read More

Software abstraction is a huge benefit of a network-on-chip (NoC), but with flexibility comes the potential for runtime errors. Improper addresses and illegal commands can generate unexpected behavior. Timeouts can occur on congested paths. Security violations can arise from oblivious or malicious access attempts.

Runtime… Read More

There are a few dozen causes of semiconductor failure. Most can be lumped into one of three categories: material defects, process or workmanship issues, or environmental or operational overstress. Even when all those causes are carefully mitigated, one factor is limiting reliability more as geometries shrink – and it… Read More
