VeloceWired features a rapid EM modeling engine, based on closed-form expressions that extract distributed netlists to model the performance of bondwire interconnects. Bondwire segments are represented as 3D vectors, and appropriate RLCk models are extracted.
The procedure enables rapid and accurate modeling of complex EM effects like:
- self inductance & resistance
- mutual inductance
- high frequency resistance (Skin Effect)
- capacitive coupling
An additional feature is the annotation of inductance values back into the layout. This is extremely useful as it provides the designer with an immediate “feeling” of what has been drawn so far. Thus the designer can easily quick-fix certain wires that are likely to hinder the circuit’s performance (e.g. too long wires that introduce large inductance, parallel wires with undesired magnetic coupling, etc).
