Gerador de vídeo pseudo-aleatório sintético na verificação funcional de circuitos decodificadores de vídeo MPEG-4.

Abstract

The advent of the new VLSI technology and SoC design methodologies has brought about an explosive growth to the complexity of modern electronic circuits. As a result, the functional verification has become the main bottleneck in any digital design flow. The functional verification has two major problems: choose good stimuli and measure coverage. The industries are producing in the last years several electronic devices, capable of manipulating digital movie. The movie encoders and decoders are becoming more and more common among the consumers, popularizing the concept of the movie compression. In order to implement the functional verification of a movie decoder, the stimuli should be in a coded digital movie format. This movie should have the necessary characteristics to stimulate the decoder digital circuit properly. This work presents a solution for the problems that appeared during the functional verification of movie decoders IP-Cores. A movie generator called RandMovie has been developed; it is capable of producing random synthetic movies. With this movie generator the engineer will be capable of generating movies to be used as stimuli in the functional verification with coverage.
