Title:
A METHODE AND DEVICE FOR MODELING POWER SUPPLY NOISE
Document Type and Number:
WIPO Patent Application WO/2009/036702
Kind Code:
A1
Abstract:
A power supply noise modeling method is disclosed, for solving the problem that
the existing power supply noise model is inaccurate. The method includes: sampling
the voltage of the power testing nodes which be selected from each of the IC chips
in a single-chip; obtaining a frequency domain voltage sequences by transforming
the voltage into frequency domain; obtaining a impedance matrix based on each
of voltage testing nodes which be selected as testing ports; achieving the power
supply noise model by the inversion of the impedance matrix multiplied by the
voltage sequences. Each of the power supply noise models can be used for designing
PDS accurately, and can reduce the cost of the design in PDS.
