Design problems that appear in the late phases of the development cycle can be extremely difficult to track down and debug, thus putting project schedules at risk. It's not uncommon for an engineer to run the verification test on what appears to be the main design problem, only to find the problem in the dump. Traditional debug techniques don't always help to localize the issue. This whitepaper presents the concept of debugging with “real time dump” using Verdi Transaction Debug Platform (protocol analyzer, nWave, nTrace) and show its benefits by taking a few generic USB protocol problem statements and solutions using the same tools, including how it can vastly reduce the amount of time needed to track down design problems. In addition, this paper introduces additional benefits available with Transaction and Protocol Analyzer, such as synchronization with signal and source code and running the tool in interactive mode.
