FPGA layout method and macro element

Abstract

The invention relates to a FPGA layout method and a macro element. The method comprises steps of: determining multiple stages of multiplexers with a unique determined path and between a first-stage input and a last-stage output, wherein the multistage multiplexer includes at least two stages of multiplexers, each stage of multiplexers includes one or more multiplexers; packaging the multiple stages of multiplexers into a macro element, wherein the input of the macro element is the first-stage input and the output of the macro element is the last-stage output; establishing nodes according to the input and the output of the macro element, setting a layout model, and performing layout according to the layout model.

AI Technical Summary

Benefits of technology

This technology allows an ASIC (Application Specific Integrated Circuit) chip designer or programmer to create customized circuits on their own computer without having to manually program them through complex programming languages like C/C++ programs. It also simplifies the routing processes needed when connecting different components together within these circuits. By embedding this circuit design data inside each layer of the device's semiconductor substrate, it becomes easier than ever before to perform detailed simulation analysis due to its unique route from one level to another. Overall, this new technique helps reduce costs associated with laying out integrated circuits while still maintaining high efficiency.

Problems solved by technology

This patented describes how complex electronic devices such as field programmable gate array(FPGAs), have become increasingly important for use across different industries due to their ability to perform various functions quickly and efficiently while being compacted into smaller sizes. However, current methods require manual intervention when create these circuits, leading to increased complexity and cost overruns. Therefore, it becomes crucial to develop efficient techniques by automatically optimizing circuit placement within this type of semiconductor chip called FPGASA.
