Abstract: PURPOSE:To improve the designing efficiency of an electronic circuit by correcting automatically a circuit diagram so as to obtain the desired characteristic when an operational amplifier circuit is designed. CONSTITUTION:When an operational amplifier circuit is designed, a 1st comparison part compares the circuit simulation result with the expected value. The result of this comparison is compared with the result of comparison obtained from the preceding circuit simulation in the same way via a 2nd comparison part. Then it is decided whether the calculation should be carried on or not. At the same time, a deciding part decides whether the circuit simulation result is coincident with the expected value or not based on the result obtained via the 1st comparison part and a condition file. When no coincidence is obtained, the circuit diagram data is corrected with use of a rule file. As a result, the circuit diagram data can be automatically corrected.
