Optimization of IBIS-AMI Model Parameters with Machine Learning Algorithms

This article describes the use of Cadence’s Sigrity signal and power integrity solution ML optimization algorithm to quickly and efficiently converge on the best set of parameters in a set of IBIS-AMI models. The application of Sigrity was investigated for refining IBIS- AMI parameters to find the optimal set of values to maximize a specific metric.

Mitigating Ground Loop Errors in High-Current PDN Measurements: Validating Measurement Accuracy Across Oscilloscope Platforms

As currents increase and voltage rails shrink, managing fluctuations becomes a critical challenge. While probe noise is a major factor, the common-mode noise induced by the ground loop between the high-current DUT and the oscilloscope is often the more dominant disruptor in high-current AI environments. This experiment proves that simply switching oscilloscope vendors will not solve the problem. Read on to learn why the solution lies in the probing chain.
