Abstract

Various aspects of a technology disclosed herein relate to thermal model obfuscation. A thermal model for a first assembly is received. An obfuscated thermal model is then generated from the thermal model. The generation comprises replacing name or names associated with one or more objects in the first assembly with obfuscated names. The obfuscated thermal model can be used in a thermal simulation of a second assembly, of which the first assembly is a component.

Claims (39)

1. A method, executed by at least one processor of a computer, comprising:

receiving a thermal model for a first assembly;

generating an obfuscated thermal model from the thermal model, wherein the generating comprises: replacing name or names associated with one or more objects in the first assembly with obfuscated names, and removing annotations in the thermal model; and

storing the obfuscated thermal model for being used in a thermal simulation of a second assembly, of which the first assembly is a component.

2. The method recited in claim 1 , further comprising:

performing the thermal simulation on the second assembly based on the obfuscated thermal model.

3. The method recited in claim 1 , further comprising:

storing information of the thermal model and information of the obfuscated thermal model in a cross-referenced way.

4. The method recited in claim 1 , wherein the generating further comprises:

varying one or more parameters in the thermal model within a predetermined range.

5. The method recited in claim 1 , wherein the generating further comprises:

varying two or more parameters in the thermal model such that effects on thermal properties are cancelled out.

6. The method recited in claim 1 , wherein the first assembly is a chip package.

7. One or more non-transitory computer-readable media storing computer-executable instructions for causing one or more processors to perform a method, the method comprising:

receiving a thermal model for a first assembly;

generating an obfuscated thermal model from the thermal model, wherein the generating comprises: replacing name or names associated with one or more objects in the first assembly with obfuscated names, removing annotations in the thermal model; and

storing the obfuscated thermal model for being used in a thermal simulation of a second assembly, of which the first assembly is a component.

8. The one or more non-transitory computer-readable media recited in claim 7 , wherein the method further comprises:

performing the thermal simulation on the second assembly based on the obfuscated thermal model.

9. The one or more non-transitory computer-readable media recited in claim 7 , wherein the method further comprises:

storing information of the thermal model and information of the obfuscated thermal model in a cross-referenced way.

10. The one or more non-transitory computer-readable media recited in claim 7 , wherein the generating further comprises:

varying one or more parameters in the thermal model within a predetermined range.

11. The one or more non-transitory computer-readable media recited in claim 7 , wherein the generating further comprises:

varying two or more parameters in the thermal model such that effects on thermal properties are cancelled out.

12. The one or more non-transitory computer-readable media recited in claim 7 , wherein the first assembly is a chip package.

13. A system, comprising:

one or more processors, the one or more processors programmed to perform a method, the method comprising:

receiving a thermal model for a first assembly;

generating an obfuscated thermal model from the thermal model, wherein the generating comprises: replacing name or names associated with one or more objects in the first assembly with obfuscated names, removing annotations in the thermal model; and

storing the obfuscated thermal model for being used in a thermal simulation of a second assembly, of which the first assembly is a component.

14. The system recited in claim 13 , wherein the method further comprises:

performing the thermal simulation on the second assembly based on the obfuscated thermal model.

15. The system recited in claim 14 , wherein the method further comprises:

storing information of the thermal model and information of the obfuscated thermal model in a cross-referenced way.

16. The system recited in claim 14 , wherein the generating further comprises:

varying one or more parameters in the thermal model within a predetermined range.

17. The system recited in claim 14 , wherein the generating further comprises:

varying two or more parameters in the thermal model such that effects on thermal properties are cancelled out.
