Abstract:

In the design of Power Distribution Net （PDN）, As for the rapid selection of the decoupling capacitors of multichip, this paper proposed for a new method for it. This method can make the PDN impedance lower than the target impedance, without excessive design. Aimed at the PDN with multichip, this paper adopts an optimized algorithm of Frequency Domain Target Impedance （FDTI）, and give a scheme which can select decoupling capacitors on type and quantity. Through the simulation of GUI interface, we find that this algorithm can apply to the multiple chip effectively, and it has a great engineering value.
