Abstract
An electronic drawing generation apparatus includes: a shape determination section to determine a necessary part, which needs to be subjected to simulation, in a substrate serving as a simulation target; and a shape edit section to cut out the necessary part determined by the shape determination section from an input electronic drawing so as to prepare an output electronic drawing. The shape determination section includes a design rule check section to determine a design-rule violating part as the necessary part based on design rules stored in a design rule database.
Claims9
An electronic drawing generation apparatus that generates an electronic drawing given to an electromagnetic field simulator for analyzing an electric field and a magnetic field of a substrate where a circuit is formed based on the electronic drawing,
- the apparatus comprising:
- a shape determination device that determines a necessary part in the substrate, the necessary part needing to be subjected to simulation by the electromagnetic field simulator;
- a shape edit device that cuts out the necessary part determined by the shape determination device;
- a storage storing a design rule database that includes design rules;
- and
- a storage storing an analysis technique database that includes a list of analysis techniques complying with the electromagnetic field simulator,
- wherein the shape determination device includes
- a design rule check section that determines a design-rule violating part as the necessary part, the design-rule violating part being a part violating the design rules included in the design rule database, and
- a necessary shape determination section that determines the necessary part based on the design-rule violating part and the analysis techniques included in the analysis technique database.
A method for generating an electronic drawing using a computer, the electronic drawing being given to an electromagnetic field simulator for analyzing an electric field and a magnetic field of a substrate where a circuit is formed based on the electronic drawing,
- the method comprising:
- a check step of performing by a design rule check section included by a shape determination device, a check to an input electronic drawing, which is inputted, based on design rules stored in a storage of a design-rule database, the check being performed to determine a design-rule violating part as a necessary part which needs to be subjected to a simulation;
- a necessary shape determination step of performing, by a necessary shape determination section included by the shape determination device, a necessary-part determination after the check step, the necessary-part determination being performed to determine the necessary part based on the design-rule violating part and an analysis technique stored in a storage of an analysis technique database;
- and
- an edit step of performing, by a shape edit device, an edit that cuts out the necessary part after the necessary shape determination step.
A program product stored in a non-transitory computer readable storage medium comprising instructions for execution by a computer, the instructions being for generating an electronic drawing given to an electromagnetic field simulator for analyzing an electric field and a magnetic field of a substrate where a circuit is formed based on the electronic drawing,
- the instructions comprising:
- a check step of performing by a design rule check section included by a shape determination device, a check to an input electronic drawing, which is inputted, based on design rules stored in a storage of a design-rule database, the check being performed to determine a design-rule violating part as a necessary part which needs to be subjected to a simulation;
- a necessary shape determination step of performing, by a necessary shape determination section included by the shape determination device, a necessary-part determination after the check step, the necessary-part determination being performed to determine the necessary part based on the design-rule violating part and an analysis technique stored in a storage of an analysis technique database;
- and
- an edit step of performing, by a shape edit device, an edit that cuts out the necessary part after the necessary shape determination step.
