Effective method to simulate Crosstalk between high density IO traces in high performance FPGA packages

Abstract

In this Paper, we propose a Quick Crosstalk Estimation Methodology by using Crosstalk Superposition Theory. An existing FPGA device package was chosen as the real test case for this study. For both microstrip and stripline, the designs were modeled by using Ansoft SI2D extractor, and the mutual matrix models extracted were used in crosstalk simulation conducted by using Agilent Advance Design System (ADS). The crosstalk simulation results were then compared with the crosstalk results calculated by using the new crosstalk estimation method. We summarize this paper by evaluate the effectiveness and applicability of this proposed methodology in FPGA package with high IO density.
