摘要： A system and method for using a computer system to determine the desired decoupling components for stabilizing the electrical impedance in the power distribution system of an electrical interconnecting apparatus, including a method for measuring the ESR for an electrical device, a method for determining a number of desired decoupling components for a power distribution system, and a method for placing the desired decoupling components in the power distribution system. The method creates a model of the power distribution system based upon an M×N grid for both the power plane and the ground plane. The model receives input from a user and from a database of various characteristics for a plurality of decoupling components. The method determines a target impedance over a desired frequency range. The method selects decoupling components. The method determines a number for each of the decoupling components chosen. The method places current sources in the model at spatial locations corresponding to physical locations of active components. The method optionally also places a power supply in the model. The method selects specific locations in the model to calculate transfer impedance values as a function of frequency. The method effectuates the model to determine the transfer impedance values as the function of frequency at the specific locations previously chosen. The method then compares the transfer impedance values as the function of frequency at the specific locations to the target impedance for the power distribution system.

摘要： A programmable electronic calculator is provided having a manually operable annuity switch with begin- and end-position settings, enabling a user to specify the type of annuity calculation to be performed. When the switch is set to the begin position, the annuity calculation is performed with payments due at the beginning of each payment period; when the switch is set to the end position, the annuity calculation is performed with payments due at the end of each payment period. The annuity calculation is performed under control of a routine stored in a read-only-memory (ROM) of a data processing unit.

摘要： A system and method for determining the required decoupling capacitors for a power distribution system using an improved capacitor model. In one embodiment, a method for determining the decoupling capacitors for a power distribution system includes creating a model of the power distribution system using circuit simulation software, such as SPICE. The power distribution system model includes a plurality of cells interconnected at predetermined nodes. The method then selects one or more decoupling capacitors for the power distribution system. The decoupling capacitors are represented in the power distribution system model by a capacitor model, which is a mathematical model of an electrical circuit. The electrical circuit upon which the capacitor model is based is a ladder circuit. Following the selecting of the decoupling capacitors, the power distribution system model is update based on the selections, and operation of the power distribution system is then simulated. During the simulation, transfer impedance values are determined for each of the nodes, and compared to target impedance. The method is then repeated until each of the transfer impedance values is at or below the target impedance.

摘要： A system and method for determining the desired decoupling capacitors for power distribution systems having frequency dependent target impedance. In one embodiment, the target impedance may be a function of frequency, and thus may vary in value over a frequency range from 0 Hz to a corner frequency. A specific quantity of decoupling capacitors may be selected to provide decoupling for the power distribution for a given frequency within the frequency range. A total impedance provided by the specific quantity of selected decoupling capacitors may be calculated and compared to the calculated target impedance for the given frequency. If the total impedance provided by the specific quantity of selected decoupling capacitors is greater than the target impedance for the given frequency, the impedance may be adjusted by changing the quantity of capacitors. Capacitors may continue to be added until the total impedance is less than the target impedance. This may be performed for one or more frequencies within the calculated frequency range.

摘要： A system and method for analyzing simultaneous switching noise. In one embodiment, a model may be provided for the electronic circuit to be analyzed. The electronic circuit may be an integrated circuit, a multi-chip module, a printed circuit assembly, or other type, and may in some embodiments include combinations of these types. The electronic circuit may include a plurality of drivers, each of which may be coupled to a power plane, a ground plane, and a transmission line. The connection of the driver may be accurately modeled in this manner. Each driver may be configured to switch between a logic high voltage and a logic low voltage. The modeled electronic circuit may also include a voltage source coupled to the power plane and the ground plane, a voltage regulator module, and a plurality of decoupling capacitors. The simultaneous switching of a plurality of drivers, from a logic high to a logic low, or vice versa, may be simulated. The system and method may then allow for the calculation of solutions for the transmission line and the power planes (as will be detailed below). The transmission line solution and power plane solution may be superimposed on each other, which may allow for an analysis of plane bounce, which may include one or more fluctuations in the voltage between the power plane and the ground planes.
