This paper proposes a top-down co-verification approach in the design of embedded systems composed of both hardware and software, for multimedia applications. In order to realize the optimized embedded system in cost, performance, power consumption and flexibility, hardware/software co-design becomes to be essential. In this top-down co-design flow, a target design is verified at three different levels : (1) algorithmic, (2) implementation, and (3) experimental. We have developed a methodology of top-down co-verification, which consists of the system level simulation at the algorithmic level, two type of co-simulations at the implementation level and the co-emulation at the experimental level. We have realized an environment optimized for verification performance by employing verification models appropriate to each verification stage and an efficient top-down environment by intrducing the component logical bus architecture as the interface between hardware and software. Through actual application to a image compression and expansion system, the possibility of efficient co-verification was demonstrated.
