dc.description.abstract | The post-layout gate-level simulation constitutes a critical design step for timing closure. The major drawback of traditional post-layout gate-level simulation is its long analysis time, which becomes exacerbated as design complexity increases. An alternative method is static timing analysis (STA), which can drastically reduce analysis time. However, STA sacrifices accuracy for speed and often produces unrealistic results such as false paths and overly pessimistic estimates. In this paper, we propose a hybrid analysis method that can significantly reduce analysis time, while preserving accuracy, with respect to the traditional gate-level simulation. Our key idea is that a large speedup would be possible by removing those events that are repetitious and unnecessary for simulation. In particular, we focus on reducing the number of clock-related events, which account for a major portion of all the events handled by a simulator. We tested the proposed method extensively with various benchmark circuits as well as industrial designs. Our experimental results exhibit that the proposed approach accelerates the total simulation speed by two times on average, yet maintaining the accuracy acquired by the traditional gate-level simulation. | - |
