Abstract

In modern VLSI design flow, timing analysis is crucial for verifying whether a circuit design can operate without errors. Soft-delay effect (SDE), which is a kind of degraded soft error, will make system failed though the circuit has passed the typical timing analysis. Therefore, we propose a soft-delay-aware timing analysis which takes SDE into consideration. Additionally, a path-fixing mechanism is also proposed to fix up the violated paths automatically. Experimental results show that only 1.05% area budget is required averagely that all violated paths can be fixed up. In summary, SDPTA and the path-fixing mechanism are capable of reducing SDE to general circuits without other manual effort.
