In accordance with an embodiment of the present invention, a method of serving IBIS data may include determining a circuit specified for signal integrity simulation. IBIS data may be obtained for the circuit specified, from which polynomials may be determined to be representative of at least a portion of the IBIS data. The polynomial information determined may be stored in a file with indexing for enabling its subsequent selective retrieval by way of a request for the IBIS data for the specified circuit.
In accordance with an embodiment of the present invention, two transistors are simultaneously controlled by a controller to control the application of power to a load and monitor a voltage level at the load. The controller may control the application of power to a number of loads simultaneously and may further provide voltage tracking for the loads.
