Abstract

While complete automated design is a harder problem than computer-assisted design, automated hardware reconfiguration is an even more challenging problem, because it needs to adjust to limited resources and various factors, such as noise and parasitic capacitance, a resistance and inductance. This paper presents some experimental results of on-chip automated design and reconfiguration using evolvable hardware techniques. It describes a stand-alone board level evolvable system, and its use to demonstrate on-chip synthesis of new circuits in only a few seconds. The experiments presented here indicate a recovery capability in the case of extreme environmental conditions, such as extreme temperatures, that adversely affect electronics. Some of the difficulties of dealing with the real hardware are exposed, as well as challenges more generally related to automated evolution of complex electronic systems.
