Web6 de abr. de 2012 · Introduction. Writing power intent for a design using the IEEE 1801 Unified Power Format (UPF) is generally an easy and straight-forward task. If the design will be optimized in a flat fashion (e.g. the entire design is optimized top-down in a single session), then writing the power intent is fairly simple. Situations such as being too rigid … WebLEC comprises of three steps as shown below: Setup Mode, Mapping Mode and Compare Mode. Fig-1. Logical Equivalence Check flow diagram. There are various EDA tools for performing LEC, such as Synopsys Formality and Cadence Conformal. We are considering Conformal tool as a reference for the purpose of explaining the importance of LEC.
