On the evolution of remote laboratories for prototyping digital electronic systems

Abstract

The design of digital electronic systems for industrial applications can benefit in many ways from the prototyping capabilities of field-programmable gate array (FPGA) platforms. This paper presents three evolutionary releases of an FPGA-based remote laboratory and discusses the didactical and technical motivations behind each release, aiming to reduce the overhead of setting up and operate a laboratory environment where designers and students can use FPGA prototyping to validate their designs. To achieve that, a number of abstraction layers were introduced, allowing configuration and data processing in remote FPGA platforms, as well as integrating such platforms within a simulation environment. The proposed approach supported a number of projects where groups of designers and students could specify, refine, and prototype electronic systems using a pool of remotely available FPGA platforms.
