Validating the intel pentium 4 microprocessor

Phoenix detects all the serious defects that are triggered by concurrent control signals.Moreover, it recovers from most of them, and simplifies recovery for the rest.The Stress Test engine then uses closed-loop feedback techniques to transform the Markov model into one that effectively stresses the user-selected points of interest.In parallel, Stress Test monitors the correctness of the DUT response and, if the design behaves against expectation, it reports a bug and a trace leading to it.This paper describes how we went about the task of finding bugs in the Pentium 4 processor design prior to initial silicon, and what we found along the way. For some reason we can't display an ad here, probably because of an ad blocker.

It generates random instruction sequences that are then fed in parallel to a design Manuscript received November 1, 2005; revised March 29, 2006. Given the subtle issues involved with concurrency and atomicity, however, it is important that transactional memory system ..." Transactional memory is an attractive design concept for scalable multiprocessors because it offers efficient lock-free synchronization and greatly simplifies parallel software. Abstract—The challenge of verifying a modern microprocessor design is an overwhelming one: Increasingly complex microarchitectures combined with heavy time-to-market pressure have forced microprocessor vendors to employ immense verification teams in the hope of finding the most critical bugs in a ti ..." Abstract—The challenge of verifying a modern microprocessor design is an overwhelming one: Increasingly complex microarchitectures combined with heavy time-to-market pressure have forced microprocessor vendors to employ immense verification teams in the hope of finding the most critical bugs in a timely manner.Unfortunately, too often, size does not seem to matter in verification, as design schedules continue to slip and microprocessors find their way to the marketplace with design errors.The model is generated from the user-specified template files and is used to generate the instructions sent to the design under test (DUT).In addition, the user specifies key activity nodes within the design that should be stressed and monitored throughout the simulation.
