SIMULATING DEVICE OF DIGITAL CIRCUIT

摘要

PURPOSE:To detect the error of circuit design easily by inputting directly the data of a circuit diagram, processing the circuit diagram data by data driving type graphic language and displaying the process of simulation together with the circuit diagram. CONSTITUTION:A circuit diagram input part 41 inputs a circuit diagram to be simulated by a display and a light pen in a conversational format. In a partial circuit to be frequently used out of a circuit, the detailed circuit diagram data are previously stored in a partial circuit storing part 42 and are to be used at the time of input. Data from the input part 41 and the storage part 42 are coupled each other by a partial circuit coupling part 43 to form a main coupled diagram data. A loop structure converting part 44 searches the loop structure included in the circuit diagram data, cuts off the loop and converts the cut loops into a return structure part. A dividing part 45 is divided into an operation part and a state storing part. These data are processed by a data driving type processing part 46.
