Patent ID: 8386991

Claim:
A design support apparatus comprising: a memory; and a processor that executes a procedure in the memory, the procedure including: a circuit-data generation process that generates circuit data based on layout information of a semiconductor integrated circuit; and a parameter determination process that sets a first parameter relating to mechanical stress exerted on a transistor including at least one of a plurality of gates in a diffusion region, wherein the circuit-data generation process obtains a mobility of the transistor based on the first parameter and reflects the mobility in the circuit data; wherein the parameter determination process sets the first parameter based on one of, an average value of distances from an end of the diffusion region to each of the at least one of the plurality of gates, and map data including a distance between a gate closest to the end of the diffusion region and the end, a gate pitch between the at least one of the plurality of gates, and a number of the at least one of the plurality of gates.
