System Design Methodology for Use in Design of Large-Scale Systems

摘要

The authors have investigated a system design methodology enabling multilevel design and simulation. Thid methodology involves adding a step to the currently used approach: a behavioral language model (BLM) description of a system or circuit written in the computer programming language Pascal. This BLM complements and enhances gate-level design, gives another means of communication to both system-level and design personnel, and can be compared with gate-level circuit descriptions during simulation for verification purposes. In addition to these advantages, the BLM description results in tremendous improvement in simulation computer time over gate-level circuit descriptions. The purpose of this study is to demonstrate the feasibility and benefits of applying this system design methodology to the development of most systems. The Trident II Arming Fusing and Firing (AF and F) RADAR interface was selected as an example system due to its feasibility of expression in hierarchical fashion and its complex data transmission requirements.
