Channel Design Using Microprobing and Modeling Techniques
应用文章
Complex channel topologies transmitting Gigabit data streams challenge the best digital design engineers today. Advanced error correction techniques alone are not a cure all for what ails the signal integrity of our telecommunication systems. Multiple technical disciplines and various domain analysis tools are now required to provide proper insight into performance. This application note will discuss step-by-step channel analysis methodologies using microprobing measurements with simulation and modeling tools to show accurate results to 20 GHz. A typical design case study using new international proprietary memory architecture will be discussed. We explore the key challenges to correlate microprobing measurements with coaxial measurements and modelling. Of particular interest is using advanced error correction techniques to simplify this task.
