Reducing circuit complexity to minimize design turnaround time and maximize chip area utilization is the most evident problem in dealing with VLSI layout. Three suggestions have been recommended to reduce circuit complexity. They are using regular modules as design targets, using hierarchical top-down design as a design methodology, and using CAD as a design tool. These three suggestions are the basis of this dissertation project. In this dissertation, three silicon compilers were implemented which take an universal AHPL circuit description as an input and automatically translate it into SLA (Storage Logic Array), PPLA (Path Programmable Logic Array), and ULA (Uncommitted Logic Array) chip layout. The goal is to study different layout algorithms and to derive better algorithms for alternative VLSI structures. In order to make a precise chip area comparison of these three silicon compilers, real SLA and ULA circuits have been designed. Four typical AHPL descriptions of different circuits or varying complexity were chosen as comparison examples. The result shows that the SLA layout requires least area for circuit realization generally. The PPLA approach is the worst one for large scale circuit realization, while the ULA lies in between.
