  • Grouping nets to facilitate repeater insertion
    Patent number: 11144700
    Abstract: Route segments of a set of nets may be grouped into route groups. Terminals of the set of nets may be grouped into terminal groups. For each net in the set of nets, a net signature may be determined based on route groups associated with the net and terminal groups associated with the net. The set of nets may be grouped into net groups based on the net signatures.

  • Charge-based miller coefficient computation
    Patent number: 8078447
    Abstract: A method of estimating a Miller coefficient for an aggressor network and a victim network coupled by a coupling capacitor includes synthesizing a reduced order system from the aggressor network and the victim network, estimating an active area across the coupling capacitor for an aggressor induced noise signal based on the reduced order system, calculating an estimate of the Miller coefficient based on the active area of the aggressor induced noise signal, and outputting the calculated estimate of the Miller coefficient.
