Abstract
In a procedure for the synthesis of logic circuits in which the components of the logic circuits are replaced by model instances related to data files stored in the procedure data base, a rule structure is described that permits the synthesis of the logic circuit by testing the model instances through a process included in a first or antecedent portion of the rule, and in the event that the conditions of the rule are fulfilled, then the consequence portion of the rule is executed. The consequence portion of the rule can include the replacement of one or more model instances of the logic circuit with one or more different model instances while retaining the functional or logical equivalence between the instances before and after the application of the rule. The rule includes a field that permits automatic prioritization a plurality of rules. The rules are written in a format that is similar to normal grammatical construction and, therefore, easily learned.
