Abstract

Graphical viewing of shapes and descriptive information in displayed graphical images. In one aspect, shape information is displayed in a graphical interface using a computer system and includes causing a display of an image on a display device with or more shapes, and causing a display of multiple labels on the display device. Each of the labels is associated with a different one of the displayed shapes, and the labels are derived from stored connectivity information for the one or more shapes describing the connections of the shapes.

Claims

1. A method for displaying shape information in a graphical interface, the method comprising:

using a computer system to perform the following;

causing a display of at least a portion of a design in a view on a display device, wherein one or more shapes of the design are displayed in the view;

determining a plurality of labels for display in the view on the display device, each of the labels associated with a different one of the displayed shapes, wherein the labels are derived from stored connectivity information for the one or more shapes describing the connections of the shapes;

determining a display size for each of one or more shapes based at least partially on a current display zoom level of the view in the graphical interface, wherein the current display zoom level is one of a plurality of zoom levels available for the view; and

causing a display of each of the labels in the view at least partially overlaying its associated shape if the associated shape has a display size above a predetermined threshold size, wherein if the associated shape does not have a display size above the predetermined threshold size, the associated label is not displayed.

2. The method of claim 1 wherein the labels are not individually input by a user of the graphical interface.

3. The method of claim 1 further comprising receiving from a user input indicating a maximum distance or percentage of shape size that each label is allowed to be displayed overhanging a border of its associated shape.

4. The method of claim 1 wherein the shapes represent traces in a circuit layout and wherein the stored connectivity information describes electrical connectivity of the shapes and is stored in a connectivity information database, and wherein each label identifies the connectivity of the associated shape with respect to one or more components of the design.

5. The method of claim 1 further comprising:

changing the current display zoom level of the view to a new display zoom level based on a received command;

determining a new display size for each of the one or more shapes based at least partially on the new display zoom level of the view in the graphical interface; and

causing a display of each of the labels in the view at least partially overlaying its associated shape if the associated shape has a new display size above the predetermined threshold size, wherein if the associated shape does not have a new display size above the predetermined threshold size, the associated label is not displayed.

6. The method of claim 1 further comprising receiving input from the user to cause a marker to be displayed on a designated one of the shapes designated by the user, the marker always being displayed in the view regardless of the displayed size of the designated shape.

7. The method of claim 1 wherein the plurality of labels are all displayed within a predetermined zone relative to a displayed cursor controlled by a user of the graphical interface with an input device, and wherein no labels are displayed outside of the zone.

8. The method of claim 7 wherein the predetermined zone is an area centered on the displayed cursor.

9. The method of claim 7 wherein a label is displayed on the display screen only if at least a portion of the shape associated with the label is currently positioned within the zone.

10. The method of claim 1 wherein labels are repeatedly displayed for a single shape for at least one of the shapes, such that the single shape has multiple displayed labels.

11. The method of claim 10 wherein each of the labels is repeated on its associated shape if the shape extends outside a zone of focus of eyes of a user of the graphical interface.

12. The method of claim 1 wherein one or more of the labels are displayed within an area equivalent to a zone of focus of eyes of a user of the graphical interface, the display of the at least one label within the zone of focus being different than display of at least one label outside the zone of focus.

13. The method of claim 12 wherein at least a portion of one of more of the shapes are displayed within the zone of focus, wherein for one or more shapes, the associated labels are displayed as close to the center of the zone of focus as possible while overlaid on the associated shapes, and for one or more of the shapes displayed outside the zone of focus, the associated labels are displayed centered on the associated shapes.

14. The method of claim 12 wherein the zone of focus is centered on a displayed cursor that is controlled by the user using an input device.

15. The method of claim 1 wherein each of the labels is displayed having a size proportional to a height, or a width, of its associated shape.

16. The method of claim 1 wherein the design is a circuit design, and wherein causing the display of each of the labels in the view includes filtering the display of each of the labels such that if the associated shape is associated with at least one of a plurality of predetermined functions of a circuit design, the associated label is displayed, and if the associated shape is not associated with at least one of the predetermined functions of the circuit design, the associated label is not displayed.

17. The method of claim 16 wherein the predetermined functions of the circuit design for the filtering include at least one of:

transmitting a specified signal used in the circuit design, and

connection to a specified connectivity network or component instance of the circuit design.

18. The method of claim 1 wherein causing the display of each of the labels includes hiding the display of a redundant portion of at least one of the determined labels, wherein the redundant portion is not needed to uniquely identify the shape associated with that label with respect to the other shapes.

19. A computer program product comprising a non-transitory computer readable medium including program instructions to be implemented by a computer and for displaying shape information in a graphical interface, the program instructions for:

causing a display of at least a portion of a design in a view on a display device, wherein one or more shapes of the design are displayed in the view; and

determining a plurality of labels for display in the view on the display device, each of the labels associated with a different one of the displayed shapes, wherein the labels are derived from stored connectivity information for the one or more shapes describing the connections of the shapes;

determining a display size for each of the one or more shapes based at least partially on a display zoom level of the view in the graphical interface, wherein the current display zoom level is one of a plurality of zoom levels available for the view; and

causing a display of each of the labels in the view at least partially overlaying its associated shape if the associated shape has a display size above a predetermined threshold size, wherein if the associated shape does not have a display size above the predetermined threshold size, the associated label is not displayed.

20. The computer program product of claim 19, further comprising:

changing the current display zoom level of the view to a new display zoom level based on a received command;

determining a new display size for each of the one or more shapes based at least partially on the new display zoom level of the view in the graphical interface; and

causing a display of each of the labels in the view at least partially overlaying its associated shape if the associated shape has a new display size above the predetermined threshold size, wherein if the associated shape does not have a new display size above the predetermined threshold size, the associated label is not displayed.
