Abstract

A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a process that includes: setting a starting point and a target component on a circuit of a circuit diagram; tracing lines based on connection relationship of a component located between the starting point and the target component; counting the number of lines between the starting point and the target component; determining positional relationship of components based on the counted number of the lines; and outputting information that the positional relationship is inappropriate when determination result indicates that the positional relationship is inappropriate.

Claims

1. A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

setting a starting point and a target component on a circuit of a circuit diagram;

tracing lines based on connection relationship of a component located between the starting point and the target component;

counting the number of lines between the starting point and the target component;

determining positional relationship of components based on the counted number of the lines; and

outputting information that the positional relationship is inappropriate when determination result indicates that the positional relationship is inappropriate.

2. The non-transitory, computer-readable recording medium according to claim 1, wherein

after setting the starting point and the target component, the setting sequentially sets a component where a signal from the starting point flows as the target component on the circuit of the circuit diagram,

the counting counts the number of lines from the starting point to the target component for each target component, and

the determining determines the positional relationship of components by comparing the numbers of lines of respective components set as the target components.

3. The non-transitory, computer-readable recording medium according to claim 1, wherein the counting counts the number of lines from the starting point to the target component, with each of a line between components, a line between a component and a branching point of a line, a line between branching points, and a line between a branching point and a component, being counted as one line.

4. The non-transitory, computer-readable recording medium according to claim 1, wherein

in the circuit diagram, points are arranged at equal intervals in a two-dimensional manner, and a circuit indicated by the connection relationship of components in conformity to the points, and

the counting processing counts the number of lines from the starting point to the target component with a line connecting the points with each other being counted as one line.

5. The non-transitory, computer-readable recording medium according to claim 1, wherein for a second component which is in inappropriate positional relationship when a distance from the starting point is shorter than a first component, the determining determines that the positional relationship is inappropriate even when the number of lines of the first component and the number of lines of the second component are equal to each other.

6. A detection method comprising:

setting, using a computer, a starting point and a target component onto a circuit of a circuit diagram;

tracing, using the computer, lines based on connection relationship of a component located between the starting point and the target component;

counting, using the computer, the number of lines between the starting point and the target component;

determining, using the computer, positional relationship of the component based on the counted number of the lines; and

outputting information that the positional relationship is inappropriate when determination result indicates that the positional relationship is inappropriate.

7. An information processing apparatus comprising:

a memory;

a processor coupled to the memory and configured to;

set a starting point and a target component onto a circuit of a circuit diagram;

trace lines based on connection relationship of a component located between the starting point and the target component;

count, using the computer, the number of lines between the starting point and the target component;

determine positional relationship of the component based on the counted number of the lines; and

output information that the positional relationship is inappropriate when determination result indicates that the positional relationship is inappropriate.

8. A computer-implemented method of circuit design comprising:

establishing a starting point within the circuit diagram including a plurality of components;

setting one of the plurality of components as a target component;

tracing lines from the starting point to the set target component;

counting the number of lines between the starting point and the target component;

determining a positional relationship of the target component based on the counted number of lines; and

outputting a result indicating appropriateness of the determined positional relationship of the target component based on rule information for the target component and the counted number of lines.

9. The method according to claim 8, further comprising:

collecting component data of a plurality of components included within a circuit diagram, the component data including component type, component signals input or output from components.

10. The method according to claim 9, further comprising:

storing the collected component data in a memory along with the rule information, the rule information stores a condition of a number of lines representing the positional relationship causing a defect, for each of component combinations causing the defect.

11. The method according to claim 8, wherein the result indicating further comprising:

comparing the counted number of lines with a threshold number within the rule information for the target component,

wherein the result indicating appropriateness indicates the positional relationship of the target component in inappropriate when the counted number of lines is greater than the threshold number.

12. The method according to claim 8, wherein the rule information includes the starting point, line characteristics for the plurality of components, a plurality of threshold numbers for different combinations of the plurality of components
