Remote FPGA design through eDiViDe — European Digital Virtual Design Lab

Abstract

The design and development of digital electronic systems is mainly performed by use of a hardware description language. To prepare students in electrical engineering for a career in hardware design many universities provide courses on VHDL. The traditional approach in teaching VHDL is mainly by means of textbook examples and simulation provided by software applications. These exercises are perceived as monotonous by the students and do not or only very slightly correspond with actual real-life applications based on FPGAs. Moreover, most real-life applications are too expensive to be equipped in student laboratories. To bridge the gap between a simulation-only environment and affordable real-life applications students should be provided access to remote real-life setups with a 24/7 availability and preferably shared between multiple institutes. The eDiViDe platform (European Digital Virtual Design Lab, http://www.edivide.eu), see Fig. 1, provides students with this unlimited and exciting access to FPGA based setups. Instead of theory-only courses and a quick basic lab, they can work their way through digital design courses testing their skills on real-life setups to trigger their interest. The platform hosts multiple FPGA setups at different European institutes. These setups are accessible through a web-based interface with video feedback. VHDL development is performed offline, given an entity and specific setup information. All further steps of the FPGA toolchain are performed on the platform. A reservation system takes care of the FPGA programming and student interaction with the setups. Similar initiatives provide stable solutions with educational support [1,2,3]. The eDiViDe platform differentiates with a distributed platform across several institutes and with the support for advanced setups. It is the result of a joint effort and easily expandable with additional setups at any location. At this moment following setups are available: greenhouse, stepper motor control, sea noise emulator, state machine workshop, Geffe generator, pong / game of life, traffic light control, MIPS CPU. This set will be extended with more advanced setups that include e.g. a partial reconfiguration workshop for audio/video filters, a side-channel analysis setup and a mars rover playfield. Besides promoting digital design education, the eDiViDe platform creates a channel to make the research activities in the contributing universities more visible. Industry could also benefit from this platform to promote their brand and products to soon to be engineers.
