Latest Patents

Osamn holds a patent titled "Method and system for screening a VLSI design for inductive coupling noise." This patent describes a method for estimating inductive coupling noise on a signal within a transmission line in a circuit design stored in computer memory. The method involves determining capacitive coupling noise, adding inductive coupling noise, and comparing the total to a specified maximum amount of noise. The inductive coupling is expressed as a percentage of the supply voltage, which varies based on the transition rate of the signal, the resistance of the line, and the gate capacitance of a load on the line. The method also includes creating a table of inductive coupling values for various design conditions, which is generated using a field solver and a circuit simulator.
