The design and implementation of a microprocessor architecture is a laborious activity, requiring the collaboration of hundreds of engineers and the use of dozens of development tools. During development, the implementation and testing phases are highly interconnected and interrelated. Each change made by the design team is followed by thorough testing of new functionality by the performance verification team. Effective communication between these two teams is crucial to meeting the tight timelines. Moreover, the more accurate the description of the bug found, the faster the identification of the cause and therefore the resolution of the problem. In this work, a solution for both of these aspects is proposed: an automatic performance capture mechanism to overcome the problem of promptness of the results and a new measurement system with more observation points in the device chain in order to obtain a more accurate picture.
