LOOK-UP BASED FAST LOGIC SYNTHESIS

摘要

Systems and techniques are described for performing circuit synthesis. Some embodiments create a lookup table based on information contained in a cell library. The lookup table is then used during circuit synthesis. Specifically, some embodiments optimize cells in a reverse-levelized cell ordering. For a given cell, a table lookup is performed to obtain a set of optimal cell configurations, and the cell is replaced with a cell configuration selected from the set of optimal cell configurations. Some embodiments concurrently optimize cells for timing, area, and power leakage based on the timing criticality of the cells.

1. A method for performing circuit synthesis, the method comprising:
receiving a cell in a circuit design that is to be optimized; performing, by a computer, a table lookup operation on one or more tables based on information associated with the cell to obtain a set of optimal cell configurations, wherein the one or more tables enable the set of optimal cell configurations to be looked up based on the information associated with the cell; and replacing the cell in the circuit design with a cell configuration selected from the set of optimal cell configurations.
