SID: synthesis of integral design

The author describes the SID program, a knowledge-based expert system used for the synthesis of logic designs. A system architecture is presented with several major contributions: synthesis is performed on heterogeneous sets of logic elements in their natural physical partitions. Logic design database and rule language are customized to give rules complete decision and transformation capabilities together with fast runtime. Timing and size metrics consider a plurality of path scenarios simultaneously for a fully-constrained synthesis
