On-die capacitance (ODC) is important in the design of robust power distribution network (PDN) by providing a means to minimizing the high-frequency PDN impedance. ODC is critical to mitigate high-frequency noise when other types of decoupling capacitance cannot provide necessary charge. It is challenging, however, to predict ODC accurately at full-chip level where various types of ODC including intrinsic gate capacitance and signal interconnect capacitance are a significant contributor. This work provides insights to power integrity engineers in determining ODC more accurately at different stages of the design with minor adaptations to existing CAD flows, leveraging industry standard tools.


This work provides insight to the practicing power integrity engineers in determining On-Die Capacitance (ODC) for different applications more accurately at different stages of a product design cycle with minor adaptations to existing CAD flows leveraging industry standard tools as well as practical wisdom in avoiding common pitfalls.

Intended Audience

Basic knowledge of PDN design
