dc.description.abstractThe semiconductor industry is strategically focusing on automotive markets, and significant investment is targeted to addressing these markets. Runtime better-than-worst-case designs like Razor lead to massive timing errors upon breaching the critical operating point and have significant area overheads. As we scale to higher-reliability automotive and industrial markets we need alternative techniques that will allow full extraction of the power benefits without sacrificing reliability. The proposed method utilizes positive slack available in the pipeline stages and re-distributes it to the preceding critical logic stage using Slack Balancing Flip-Flops (SBFFs). We use opportunistic under designing to get rid of the area, power and error correction overheads associated with the speculative hardware of runtime techniques. The proposed logic reshaping results in 12 percent and eight percent power and area savings respectively compared to the worst-case design approach. Compared to runtime better-than-worst-case designs, we get 51 percent and 10 percent power and area savings, respectively. In addition, the timing budgeting and timing correction using opportunistic slack eliminate critical operating point behavior, metastability issues and hold buffer overheads encountered in existing runtime resilience techniques.en_US
