Abstract
A production system for an expert system comprising: a production rule memory unit storing circuit conversion rules, each having a condition part describing circuit connection and an execution part describing a conversion of the condition part to an equivalent logic circuit dependent upon a predetermined semiconductor technology and further having a provisionally predetermined priority; a task data memory unit storing circuit connection data, each being subjected to an application of the circuit conversion rules; a production rule interpretation and execution unit for selecting a circuit conversion rule in accordance with the provisionally predetermined priority, collating the condition part of the selected circuit conversion rule with the circuit connection data to determine whether the condition part matches with a part of the circuit connection data and, when the both match each other, converting the part of the circuit connection data by the corresponding execution part of the circuit conversion rule to an equivalent logic circuit; further each production rule being provided with a rule flag indicating the collation failure to the circuit connection data, a rule flag memory uni…
