Fifteen Years of Formal Property Verification in Intel
Model checking technologies have been applied to hardware verification in the last 15 years. Pioneering work has been conducted in Intel since 1990 using model checking technologies to build industrial hardware verification systems. This paper reviews the evolution and the success of these systems in Intel and in particular it summarizes the many challenges and learning that have resulted from ...
متن کاملReplacing Testing with Formal Verification in Intel CoreTM i7 Processor Execution Engine Validation
Formal verification of arithmetic datapaths has been part of the established methodology for most Intel processor designs over the last years, usually in the role of supplementing more traditional coverage oriented testing activities. For the recent Intel Core i7 design we took a step further and used formal verification as the primary validation vehicle for the core execution cluster, the comp...
متن کاملVerification of All Circuits in a Floating-Point Unit Using Word-Level Model Checking
1 I n t r o d u c t i o n The floating-point division flaw [SB94, Coe95] in Intel Corp.'s Pentium underscores howhard the task of verifying a floating-point arithmetic unit is, and how high the cost of a floating-point arithmetic bug can be. About one trillion test vectors were used and none uncovered the bug. The recall and replacement of the chips in the field cost Intel $470 million. Since t...
متن کاملFormal Verification of an Intel XScale Processor Model with Scoreboarding, Specialized Execution Pipelines, and Imprecise Data-Memory Exceptions
simulator TLSim [41], takes the specification and impleWe present the formal verification of an Intel XScale processor model. The XScale is a superpipelined RISC processor with 7-stage integer, 8-stage memory, and variable-latency multiply-and-accumulate execution pipelines. The processor uses scoreboarding to track data dependencies, and implements both precise and imprecise exceptions. Such s...
متن کاملWeb Service Choreography Verification Using Z Formal Specification
Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...
