Abstract :
A description is presented of the high-level and logic synthesis stages in the digital design automation system DIADES. High level design, namely, data path synthesis, and control unit synthesis start from a parallel program graph, the form of description that includes both the control-flow and the data-flow graph. While the data path is allocated and scheduled, the control unit is designed to be composed of either microprogrammed units or finite-state machines. The latter are minimized in two dimensions (states and inputs), assigned and realized in logic. Several logic synthesis procedures, respective to various design styles and methodologies, can be used to design combinational parts of state machines, microprogrammed units, and data path logic
