Abstract

A method for visually verifying an implementation of a design is described. The method includes integrating logical design data, physical design data, and physical implementation data into a common data format and graphically displaying the commonly formatted data to provide a visualization of the design, the visualization including a spatial context component associated with the physical implementation data.

Claims

1. A method for visually verifying a design of a wire system, said method comprising using a computer to:

retrieve logical design data associated with the wire system, and physical design data associated with the wire system;

extract data from a 3D computer model of the wire system;

convert the retrieved logical and physical design data and the extracted data into a common data format;

perform a difference analysis of the logical and physical design data with the extracted data from the 3D model to identify any non-conformances between the 3D model and the design data; and

graphically display any non-conformances.

2. The method according to claim 1 wherein the wire system includes a wire harness assembly.

3. The method according to claim 2 wherein the analysis includes tracing each individual wire in the wire harness assembly to ensure that wire harness routing is complete.

4. The method according to claim 1 wherein the 3D model indicates function, layout, and planned location of the wire system.

5. The method according to claim 1 wherein the logical data is accessed from wiring diagrams and schematics of the wire system.

6. The method according to claim 1 wherein performing the differences analysis and displaying the non-conformances are part of verification and validation of an aircraft wiring system design.

7. The method according to claim 1 further comprising graphically displaying information about the 3D model in a tree view.

8. The method according to claim 1 wherein the non-conformances include at least one of missing design information and spatial requirement violations.

9. The method of claim 1, wherein the 3D computer model is generated from a logical construct, and wherein at least some of the retrieved logical design data includes data that is not found in the logical construct.

10. The method of claim 1, wherein the logical design data includes a schematic of a wire system and the physical design data includes layout and location of wires in the wire system.

11. One or more computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

receive physical design data, and logical design data associated with a wire system;

extract data from a 3D computer model of the wire system;

convert the retrieved logical and physical design data and the extracted data into a common data format;

perform a difference analysis of the logical design data and the physical design data with the extracted data from the 3D computer model to identify any non-conformances between the design data and the 3D computer model; and

generate a visualization of the non-conformances on a user interface.

12. One or more computer-readable storage media according to claim 11 wherein the logical data is accessed from wiring diagrams and schematics of the wire system.

13. One or more computer-readable storage media according to claim 11 wherein the design data also includes functional design data;

and wherein the functional design data is also compared to the data extracted from the 3D computer model.

14. One or more computer-readable storage media according to claim 11 wherein the non-conformances include at least one of missing design information and spatial requirement violations.

15. A computer system for verifying a design of a wire system, said computer system comprising a computer programmed to:

collect physical design data, and logical design data associated with the wire system;

extract data from a 3D computer model of the wire system;

convert the retrieved logical and physical design data and extracted data into a common data format;

perform a difference analysis of the logical and physical design data with the extracted data; and

graphically display any non-conformances between the design data and the data extracted from the 3D model.

16. The computer system according to claim 15 wherein the wire system includes a wire harness assembly.

17. The computer system according to claim 16 wherein the difference analysis includes tracing each individual wire in the wire harness assembly to ensure that wire harness routing is complete.

18. The computer system according to claim 17 wherein the logical data is accessed from wiring diagrams and schematics of the wire harness assembly.

19. The computer system according to claim 15 wherein the computer is further programmed to graphically display information about the wire system in a tree view.

20. The computer system according to claim 15 wherein the non-conformances include at least one of missing design information and spatial requirement violations.
