Smith","doi":"10.1109/EPEP.1999.819217","DOIUrl":"https://doi.org/10.1109/EPEP.1999.819217","url":null,"abstract":"The simultaneous switch noise (SSN) problem has traditionally been thought of as an inductance problem. When many drivers on a Si chip switch at the same time, current crowds into the chip ground or V/sub dd/ inductance. Ground bounce occurs proportional to the inductance in the ground or V/sub dd/ lead and the rate of change of current. This line of thinking has been effective at solving SSN problems for lead frame packages. However, packaging has progressed to packages with power and ground planes. Package traces behave more like transmission lines with impedance and delay rather than lumped inductors. The signal waveform rise and fall times are so fast that an edge may fit within the package. Wire bonds have been replaced by solder bumps and peripheral leads have been replaced by solder balls. The new structures may have less than 1% of the inductance of the packages in use just a few years ago. Capacitive and resistive elements have been added to inductance matrices to account for the package time delay and losses, but the number of circuit elements in an SSN analysis and the increased number of simultaneously switching drivers have resulted in large, complex simulation runs that require much CPU time and computer resources. It has become harder to find meaningful model to hardware correlation for large SSN problems. It is time to consider a radically new approach to simulating the SSN problem. This paper looks at treatment of the SSN problem as a power plane bounce problem.","PeriodicalId":299335,"journal":{"name":"IEEE 8th Topical Meeting on Electrical Performance of Electronic Packaging (Cat.

To include the interaction, this paper provides an integrated model for a discrete capacitor mounted on pads over vias connected to power/ground planes with degassing holes. The mutual inductance between capacitor pads, vias, and power/ground planes are completely modeled. Our modeling results show that the mutual inductance drastically changes the total loop inductance as compared to the self inductance of the capacitor. In some cases, it even reduces the total effective loop inductance. To validate the integrated modeling method, a test package is built. A measurement technique is introduced to evaluate the total loop inductance of the test package with various capacitors. The predicted results matched very well with measured data which give a high confidence on this predicting model and demonstrate the importance of modeling the interaction between capacitors, vias, and planes.","PeriodicalId":299335,"journal":{"name":"IEEE 8th Topical Meeting on Electrical Performance of Electronic Packaging (Cat.
