Abstract
The input for a test generator is a plurality of test templates, each of which typically aims at covering a specific verification task. Test templates direct the production of distinct transactions, which are the atomic functional building blocks of the design-under-verification. Test templates directed to different hardware functions of the scenario are dynamically interleaved. In this way several transactions are combined together in complex statements in order to achieve a complex test scenario. The transactions are submitted to the test generator, which generates test cases, in which the different hardware functions of the scenario are exercised in combinations. Variation among the test cases is achieved through a large number of random decisions made during the generation process.
