Power decoupling circuit generating system and power decoupling circuit generating method

摘要

Disclosed is a power decoupling circuit generating system and method capable of easily generating a power decoupling circuit for each device such as an LSI. On the basis of information regarding parameters of generating a power decoupling circuit held in a capacitor parts library and a line calculation parameter file, a power decoupling circuit of a pi-type low pass filter construction having first and second decoupling capacitors to be added to a power supply terminal of a device as a target from which high frequency noise is prevented from being passed to a power plane and a power line corresponding to an inductance is automatically generated by a power decoupling circuit generating unit, thereby making calculation for generating the power decoupling circuit unnecessary.
