We recently introduced the first prototype of an Adaptive Wiring Panel (AWP) which implemented a reconfigurable switch fabric that allows dynamic routing of analog, digital, and power signals for space system applications. In this paper, we consider a complete redesign and re-implementation of the AWP system to address issues associated with scalability, reliability and real-time monitoring of the switching fabric. We demonstrate the new system using 48 cells as opposed to the 6 cells of the first AWP prototype. We make our hardware and software systems open source and provide recommendations to support further extensions to our system.

Field-programmable wiring systems refer to methods and hardware that can maintain the interconnection of components of different types. Generally, field-programmable wiring systems support the use of multidomain fabrics that can be used to route analog, power, digital signals, optical, microwave signals, etc. This paper reviews fundamental concepts associated with the practical implementation of field-programmable wiring systems. The paper also provides different implementation examples and discusses a list of challenges and recommendations for future work in this area.
