Abstract:
A new method is presented to compress switching information in large digital
circuits. This is combined with an efficient approach of generating the noise
signatures of cells in a digital library that results in an accurate and efficient approach
for estimating the noise generated in digital circuits. This method provides a practical
approach to generating the digital switching noise for simulating substrate coupling
noise in mixed-signal ICs. Orders of magnitude reduction in the memory and
simulation time are achieved using this approach without significant loss of accuracy.
