[Problem to be solved by the invention]

In the conventional design circuit analysis device described above, the analysis information provided by the device itself merely has the function of indicating compliance with the usage rules of parts and pointing out errors in usage. Later measures such as design changes are left to the designer's own design know-how or judgment, so there are cases where the solution method for the circuit design is not necessarily appropriate. However, the drawback is that the circuit design is significantly dependent on the design experience of the designer.

[Means to solve the problem]

The designed circuit analysis apparatus of the present invention includes a circuit connection analysis mechanism that provides a designer with information regarding the acceptance or failure of used components and errors in circuit design based on predetermined circuit analysis results, and at least one circuit connection analysis mechanism that stores the analysis results. The component information storage device includes one or more analysis result storage devices and a component information storage device that stores component information referred to during analysis by the circuit connection analysis mechanism, and the component information storage device stores usage rules for used components. At least one or more alternative parts information storage a! that stores alternative parts information referred to in order to provide information regarding design improvement methods based on etc. It is composed of Im.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a first embodiment of the invention. As shown in FIG. 1, this embodiment includes a circuit connection analysis mechanism 1, a control terminal 2, a magnetic disk device 3, a magnetic tape device 4, a component information storage device 5, and an alternative component information storage device. 6 and an analysis result storage device 7.

In FIG. 1, circuit information regarding the circuit to be analyzed is stored in advance as circuit connection information at the control terminal 2/magnetic disk device 3/
The data is input to the circuit connection analysis mechanism 1 via the magnetic tape device 4 or the like. Inside the circuit connection analysis mechanism 1, predetermined circuit analysis work is carried out, and the analysis results are divided into one part name,
The analysis results are stored in the analysis result storage device 7 as design information such as input connections and output connections.

Next, while referring to the component information stored in the component information storage device 5, the design information stored in the analysis result storage device 7 is analyzed regarding suitability with respect to usage rules or usage. In this case, when a violation of usage rules or misuse is discovered, information to that effect is output to the control terminal 2/magnetic disk device 3/magnetic tape device 4, etc., and the alternative parts information storage mechanism After the replacement parts information stored in 6 is searched, specific improvement methods for the violation of the rules/misuse, etc. are also output to the control terminal 2/magnetic disk device 3/magnetic tape device 4, etc. be done.

FIG. 2 is a block diagram of a second embodiment of the invention.

As shown in FIG. 2, this embodiment includes a circuit connection analysis mechanism 8, a circuit connection information creation mechanism, a control terminal 10,
It is configured to include a parts information storage device 11, an alternative parts information storage device 12, and an analysis result storage device 13.

In this embodiment, predetermined circuit connection information that has been input in advance via a magnetic disk or the like is directly input to the circuit connection analysis mechanism 8 by directly connecting the circuit connection information creation mechanism 9 and the circuit connection analysis mechanism 8. Ru. Circuit connection analysis mechanism 8
, a predetermined circuit analysis is performed at any time, and the analysis results are returned to the circuit connection information creation mechanism 9 and sent to the control terminal 1.
0 and displayed.

In this embodiment, since the circuit connection information creation mechanism 9 and the circuit connection analysis mechanism 8 are directly connected, the information input from the control terminal 10 is passed through the circuit connection information creation mechanism 9 to the circuit connection analysis mechanism 8. Since it is possible to input the circuit connection information input from the control terminal IO,
There is an advantage that the analysis is carried out immediately in a conversational format, and the control terminal 10 instantly displays whether the circuit connection information conforms to usage rules, etc., and how to improve it in the event of a violation of the rules.

The functions of the section height information storage device 11, alternative parts information storage device 12, and analysis result storage device 13, which correspond to the functions of the circuit connection analysis mechanism 8, are the same as in the first embodiment.
