Abstract

Methods, articles of manufacture and apparatus for testing design layouts. Design layout software may be configured to display a layout diagram in a first area of a graphical user interface (GUI) screen. Parameters for testing the layout may be entered in a second area of the GUI screen. Upon receiving one or more test parameters, the layout software may be configured to identify portions of the layout that do not conform to design rules based on the test parameters.

Claims

1. A computer implemented method for testing a layout comprising configuring one or more processors to perform an operation comprising:

providing a graphical user interface (GUI) screen comprising;

a diagram of the layout, the diagram comprising a plurality of components; and

a tool configured to receive input for scrolling through a predefined range of values;

receiving, via the tool, a value for a parameter from the predefined range of values, wherein the parameter defines a geometric rule for the plurality of components in the layout;

determining whether the plurality of components conform with the geometric rule defined by the parameter; and

upon determining that one or more components do not conform with the geometric rule, visually distinguishing the one or more components in the diagram.

2. The method of claim 1, wherein the tool comprises a slider defining the range of values and a pointer.

3. The method of claim 2, wherein receiving the value for the parameter comprises receiving a pointer event that moves the pointer to a location of the slider associated with the value.

4. The method of claim 1, wherein the tool comprises a text area illustrating a current value of the parameter.

5. The method of claim 4, wherein receiving the value of the parameter comprises receiving a mouse event comprising movement of a mouse scroller, the movement of the mouse scroller changing the value of the parameter in the text area.

6. The method of claim 1, wherein the tool comprises an indication of a threshold value for the parameter.

7. The method of claim 1, wherein the layout is associated with an integrated circuit design.

8. A computer readable storage medium comprising a program product which, when executed, is configured to perform an operation, comprising:

providing a graphical user interface (GUI) screen comprising;

a diagram of the layout, the diagram comprising a plurality of components; and

a tool configured to receive input for scrolling through a predefined range of values;

receiving, via the tool, a value for a parameter from the predefined range of values, wherein the parameter defines a geometric rule for the plurality of components in the layout;

determining whether the plurality of components conform with the geometric rule defined by the parameter; and

upon determining that one or more components do not conform with the geometric rule, visually distinguishing the one or more components in the diagram.

9. The computer readable storage medium of claim 8, wherein the tool comprises a slider defining the range of values and a pointer, and wherein receiving the value for the parameter comprises receiving a pointer event that moves the pointer to a location of the slider associated with the value.

10. The computer readable storage medium of claim 8, wherein the tool comprises a text area illustrating a current value of the parameter.

11. The computer readable storage medium of claim 10, wherein receiving the value of the parameter comprises receiving a mouse event comprising movement of a mouse scroller, the movement of the mouse scroller changing the value of the parameter in the text area.

12. The computer readable storage medium of claim 8, wherein the tool comprises an indication of a threshold value for the parameter.

13. The computer readable storage medium of claim 8, wherein the layout is associated with an integrated circuit design.

14. A system, comprising:

a memory comprising a program; and

a processor which, when executing the program, is configured to;

display a graphical user interface (GUI) screen comprising

a diagram of a layout, the diagram comprising a plurality of components; and

a tool configured to receive input for scrolling through a predefined range of values;

receive, via the tool, a value for a parameter from the predefined range of values, wherein the parameter defines a geometric rule for the plurality of components in the layout;

determine whether the plurality of components conform with the geometric rule defined by the parameter; and

upon determining that one or more components do not conform with the geometric rule, visually distinguish the one or more components in the diagram.

15. The system of claim 14, wherein the tool comprises a slider defining the range of values and a pointer.

16. The system of claim 15, wherein the processor is configured to receive the value for the parameter by receiving a pointer event that moves the pointer to a location of the slider associated with the value.

17. The system of claim 14, wherein the tool comprises a text area illustrating a current value of the parameter.

18. The system of claim 17, wherein the processor is configured to receive the value of the parameter by receiving a mouse event comprising movement of a mouse scroller, the movement of the mouse scroller changing the value of the parameter in the text area.

19. The system of claim 14, wherein the tool comprises an indication of a threshold value for the parameter.

20. The system of claim 14, wherein the layout is associated with an integrated circuit design.
