Arithmetic circuits are some of the most common circuits, yet building generators for these circuits is usually both ad-hoc and error-prone. Often, generator designers do not directly use Register Transfer Languages, but instead use scripting languages (e.g., Perl) to generate RTL and overcome the limited expressivity of typical RTL languages. The authors present a new approach to generator construction, where the design language is natural and expressive, and designers are provided with special facilities to alleviate typical sources of errors. This builds on previous work, where designers write an incomplete design (a sketch) and provide a functional reference; a complete, correct design is then synthesized.
