Title: Cmos tapered gate and synthesis method
Inventor: CURRAN BRIAN W
IPC: G06F17/50
Filed: 2002-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a tapered gate and a synthesis method for improving the quality of synthesized circuit mounting. SOLUTION: A high-performance gate library is augmented with tapered gates. The widths of the stacked devices are varied to reduce delay through some of input pins. For example in a tapered NAND gate, the bottom devices in a NFET stack are to have longer widths than the top device to achieve smaller top input to output pin delay at the expense of larger bottom input to output pin delay. The method of using synthesis algorithms modifies an input net to gate pin connections and swaps traditional non-tapered gates with tapered gates to improve the delay of timing critical paths. The latest arriving gate input net is swapped with a net connected to the top pin. The gate is then converted to a tapered gate and is given paths going through the bottom gate input(s) that are not timing critical.
