Towards Signal-Power Integrity Analysis by Efficient Power Delivery Network Lumped Models Obtained From Parameter Extraction

The combined signal integrity (SI) and power integrity (PI) design process is getting more relevant and complex as a result of the continuous computing system performance growth. This complexity drives longer design cycle times using traditional tools and methods. In this paper, a low computational cost optimization method based on a parameter extraction (PE) technique is proposed to develop accurate and fast power delivery network (PDN) lumped models. Once this model is available, it is used in the simulation process during the SI and PI analysis, making the whole design process much more efficient. Our proposed methodology is applied to a classical dual data rate (DDR) memory sub-system problem, saving 99.8% of the analysis time with only 1.2% of the computational resources typically used in current industrial practices.
