  • Transistor level circuit simulator using hierarchical data
    Patent number: 6577992
    Abstract: Methods and apparatus for generating a hierarchical representation of a circuit include obtaining a netlist corresponding to the circuit, the circuit including a plurality of subcircuits. A hierarchical representation of the circuit is then generated from the netlist, the hierarchical representation including the plurality of subcircuits arranged among a plurality of levels of the hierarchical representation. Each one of the plurality of subcircuits has an associated subcircuit definition. In addition, each of a plurality of subsets of the subcircuits share a same subcircuit definition, where memory storage for the same subcircuit definition is shared by the subcircuits in each of the subsets. Moreover, each one of the plurality of subcircuits has a dynamic voltage state.
