Design automation technology for codesign: status and directions

Computer-aided design tools and design automation for hardware/software codesign have developed to the point that commercial tools supporting codesign activities are under development or in use. The current state of codesign technology and specific needs in codesign tools and environments in the future are discussed. The architecture design and assessment system (ADAS) developed at Research Triangle Institute was the first implementation reported in the literature that supported the concurrent or cooperative design of hardware and software. The ADAS model is the basic approach used to date by codesign tools. Hardware synthesis systems, modeling paradigms, design metrics, and scaling-up techniques are discussed
