The automatic synthesis of an IBM 801 processing unit using the Yorktown silicon compiler is presented. The underlying design process model is explained showing the intermediate stages, while emphasizing high-level issues. First, the principles of operations are translated manually into high-level behavioral descriptions. The system is decomposed by the designer into concurrent modules (in the 801, four pipeline stages). Structural synthesis automatically generates a circuit structure for each pipeline stage, including the control and the data path. The combinational logic is optimized globally during logic synthesis producing a multilevel implementation. The resulting size (in number of transistors) and the performance of the processor (estimated cycle time and cycles per instruction) are compared to a manual RT-level design.
