Patent ID: 8250506

Claim:
A method of determining the electromagnetic characteristics of bondwires in an electrical circuit, comprising the steps of: defining, using a computer including a non-transitory computer readable medium and processor, a position of a bondwire in an electrical circuit layout; defining a 3D position of the bondwire in the electrical circuit layout; representing the bondwire by one or more discrete segments; determining electromagnetic characteristics including inductance, resistance and capacitive coupling, of each of the segments, as a single workflow process thereby to determine overall electromagnetic characteristics of the bondwire, using a procedure comprising the steps of calculating the resistance, self inductance and self capacitance for each segment using closed-form equations selecting a pair of segments projecting the segments using vector analysis onto a common plane; and calculating using closed form equations at least one of the mutual inductance between the segments using their projections onto the common plane, and the coupling capacitance between the segments using their projections onto the common plane; and repeating the above steps for all pairs of segments.
