Abstract

A design rule management method implemented in a rule verification apparatus for checking a violation against a design rule which specifies a part shape when there is any change in parameters in a system, the rule verification apparatus including: a processing unit for processing information; an input unit for inputting information; and a storage unit for storing a first design rule, a second design rule and relationship strength therebetween in association with one another, the method allowing the processing unit to perform steps including: acquiring the changed parameter via the input unit; and in a rule verification to determine whether or not there is any violation in the design rules that use the changed parameter, acquiring from the storage unit all the design rules having the relationship strength of a predetermined value, and performing the rule verification on all the acquired design rules.

Claims

1. A design rule management method implemented in a rule verification apparatus for checking a violation against a design rule which specifies a part shape when there is any change in parameters in a system,

the rule verification apparatus comprising:

a processing unit for processing information;

an input unit for inputting information; and

a storage unit for storing a first design rule, a second design rule and relationship strength therebetween in association with one another,

the method allowing the processing unit to perform steps comprising;

acquiring the changed parameter via the input unit; and

in a rule verification to determine whether or not there is any violation in the design rules that use the changed parameter, acquiring from the storage unit all the design rules having the relationship strength of a predetermined value, and performing the rule verification on all the acquired design rules.

2. The method according to claim 1, further comprising:

displaying, when the acquired parameter violates any one of the design rules, a message indicating a rule violation occurs in the design rule on a displaying unit.

3. The method according to claim 1, wherein the rule verification apparatus is capable of communicating with a client terminal and displays, when the acquired parameter violates any one of the design rules, a message indicating a rule violation occurs in the design rule on a displaying unit of the client terminal.

4. A design rule management program recorded in a computer readable recording medium which performs the method according to claim 1.

5. A rule verification apparatus for checking a violation against a design rule which specifies a part shape when there is any change in parameters in a system,

the rule verification apparatus comprising:

a processing unit for processing information;

an input unit for inputting information; and

a storage unit for storing a first design rule, a second design rule and relationship strength therebetween in association with one another, wherein

the processing unit;

acquires the parameter which is changed via the input unit;

in a rule verification to determine whether or not there is any violation in the design rules that use the changed parameter, acquires from the storage unit all the design rules having a predetermined value in the relationship strength with the design rule using the acquired parameter, and performs a rule verification on all the acquired design rules.
