Abstract
We propose a propagation delay model for SRAM-based FPGAs. It is a sim plified Elmore delay model with a linear fan-out function. Therefore, the computational complexity is small. In order to ensure calculation accuracy, the model parameters are extracted from real layout data. Th e average model error is 4% compared to actual delays. The model is ap plicable for delay estimation in a router and as a tool for static cal culation of critical path delay.
