This paper addresses theoretical aspects of arithmetic circuit verification based on algebraic rewriting. Its goal is to advance the understanding of algebraic techniques for arithmetic circuit verification in the context of symbolic computer algebra. The paper offers a new insight into the arithmetic circuit verification problem, by viewing the computation performed by the circuit as the flow of digital data. In the proposed bit-flow model, the circuit is modeled as a network of logic components satisfying a bit-flow conservation law. We prove that the value of the flow of data in the circuit is invariant throughout the circuit and use this to prove soundness and completeness of the rewriting technique, independently from the computer algebra arguments. The efficiency of the method is illustrated with impressive results for large integer multipliers. The verification system and benchmarks are offered in an open source software environment.

Requirements elicitation is one of the essential steps towards software design and construction. Business analysts and stakeholders often face challenges in gathering or conveying key software requirements. There are many methods and tools designed by researchers and practitioners but with the persistent development of new technologies, there is a need to make requirements gathering and design‐rationale process more efficient and adaptable. Storytelling is an emerging concept and researchers are witnessing its effectiveness in education, community building, information system, and requirement elicitation. Objectives of this study are to devise a method for requirements elicitation and improving design‐rationales using story‐based techniques and evaluate the effectiveness of the proposed activity. To answer the research objectives, the authors have conducted open‐ended interviews to get feedback on the proposed method; the authors have case requirement from a running project to map how this method can be useful; and performed empirical evaluation of the proposed card‐based activity. The estimated regression model, in our study, has shown that participants' perception about the simplicity/easiness and the joy of playing the game has an eventual positive effect on requirements elicitation through enhancing user's desire to play the game, which in turn increases the collaborative learning outcomes of the game.
