This paper presents a complete and practical methodology to comprehensively solve the X problem in RTL design. It begins by reviewing common sources of Xs, and describes how they cause functional bugs as well as unwarranted debug that prolong verification cycles. Solving the X problem helps minimize simulation and synthesis iterations and enables various design analyses (e.g. power analysis), normally performed on netlists, to begin sooner. The pros and cons of various point solutions to this problem are described. The technologies discussed include structural analysis, formal analysis, coding for X-accuracy, and simulation techniques such as random seeding of state initial values. It is essential that a complete solution address both X-optimism and X-pessimism woes as well as be applicable to all sources of Xs, facilitate debug, provide coverage analysis, and enable automation, high performance, and usability. The requirements of a complete and practical solution, based on feedback from users who deal with X issues are provided. The summary of our interaction with users is that the X problem is multi-dimensional and needs a holistic solution that brings to bear the combination of structural analysis, simulation and formal analysis to solve effectively. We describe our user experiences and a case study based on our proposed solution.
