One of the emerging challenges in formal property verification (FPV) technology is the problem of deciding whether sufficient properties have been written to cover the design intent. Existing literature on FPV coverage does not solve this problem adequately, since they primarily analyze the coverage of a specification against a given implementation. On the(More)
Existing methods for formal verification coverage compare a given specification with a given implementation, and evaluate the coverage gap in terms of quantitative metrics. We consider a new problem, namely to compare two formal temporal specifications and to find a set of additional temporal properties that close the coverage gap between the two(More)
It is essential to formally ascertain whether the RTL validation effort effectively guarantees the correctness with respect to the design's architectural intent. The design's architectural intent can be expressed in formal properties. However, due to the capacity limitation of formal verification, these architectural-properties cannot be directly verified(More)
Formal property verification is increasingly being adopted by designers for module level validation. The behavior of a module is typically expressed in terms of the behavioral guarantee of the module under assumptions on its environment. Expressing such assume-guarantee properties correctly in a formal language is a nontrivial task and errors in the(More)
Practitioners of formal property verification often work around the capacity limitations of formal verification tools by breaking down properties into smaller properties that can be checked on the sub-modules of the parent module. To support this methodology, we have developed a formal methodology for verifying whether the decomposition is indeed sound and(More)
<i>Design intent coverage</i> is a formal methodology for analyzing the gap between a formal architectural specification of a design and the formal functional specifications of the component RTL blocks of the design. In this article we extend the design intent coverage methodology to hybrid specifications containing both state-machines and formal(More)
H.264 is one of the most commonly used formats for the recording, compression and distribution of video. Encoders and decoders for the H.264 standard are widely in demand, and efficient strategies for enhancing their performance have been areas of active research. With the proliferation of many core architectures in the embedded community , there has been a(More)
This paper presents a scheme for intelligent advice generation with the help of a fuzzy rule base, meant for a self-paced learner in an e-Learning environment. It employs a fuzzy machine that is fed with performance parameters e.g. score and time pertaining to a computer aided assessment of learner's learning achievement. The fuzzy machine processes these(More)
