A method for exploring the behavior of a design model, the method including the steps of providing a design model represented as a Finite State Machine (FSM). The method further includes the step of providing a path specification of interest. The method further includes the step of exploring the behavior of the design in order to find and present a scenario in the design that meets the path specification.

Target design model behavior explorer

Coverage measurement tool enabling a user to create a specific coverage tool for a coverage model including a set of coverage tasks specified by the user for checking a design such as a hardware or software system, and being associated with a database and model definition that defines the coverage model. The tool includes an insertion engine for storing into the database a table containing traces resulting from multiple tests, a processing engine processing the traces in the database according to the model definition, and a coverage analyzer analyzing the measurement results from the processing engine and preparing coverage analysis reports according to the model definition.

Coverage measurement tool for user defined coverage models

An architecture-independent test program generator for producing test programs for checking the operation of a hardware processor design comprises means for storing data representing the processor instruction set and resources, and logic for generating, for subsequent storage or processing, test programs from said stored data, characterized in that the data is a separate declarative specification, the generator comprising logic for extracting said data from the storage means, and in that the relationships between the processor resources and semantic entities associated with each instruction are modelled in said declarative specification.

Test program generator

A technique that applies the task coverage exercised within a behavioral model of the design to the design itself, while simulating one or more test sequences. Since the behavior model is an accurate and complete program representation of the architectural specification of the hardware design, the test case coverage of the architecture is implied by the measurement of how well the behavioral model code has been exercised. The completeness of the coverage is determined by the test coverage criteria selected, including, for example, statement coverage, branch coverage, or path coverage. The more detailed the criteria, the greater the number of tests.
