Abstract:
1. A computer implemented method to determine metal oxide semiconductor (MOS) gate functional limitations, the computer implemented method comprising: obtaining a plurality of slices of a MOS gate, the slices each comprising at least one parameter, the parameter comprising a slice gate width, a slice gate length and a slice stress profile; determining a drive current for each slice based on a slice gate length and a slice stress profile; summing the drive currents for each slice to form a gate drive current; determining a leakage current for each slice based on a slice gate length and a stress profile of the gate; summing the leakage currents for each slice to form a gate leakage current; and concurrently determining an effective length for the MOS gate based on the gate drive current and the gate leakage current with determining carrier mobility for the MOS gate based on the gate drive current and the gate leakage current.
