Abstract

Disclosed is a method, system, and computer program product for performing predictions for an electronic design. Embodiments of the invention allow the ability to efficiently update the model predictions at a later time once previously incomplete blocks are completed. Predictions can be efficiently updated after block designs are updated (e.g. after correcting problems detected from model predictions).

Claims

1. A computer-implemented method for performing analysis upon an electronic design, comprising:

receiving incomplete design data for an electronic design, which includes an incomplete electronic component design that is to be created in the electronic design, and information related to one or more models corresponding to a manufacturing process to be applied to manufacture the electronic design;

using a computer processor to perform model parameter determination for at least the incomplete electronic component design to generate a set of results data, wherein

the set of results data comprises simplification of one or more geometries that are not yet created for the incomplete design data rather than all geometric information of the one or more geometries; and

performing predictions of manufacturing effects for the electronic design for the manufacturing process before creation of the incomplete electronic component design, wherein

the incomplete design data is not sent in its entirety to perform the predictions.

2. The method of claim 1 in which the incomplete design data comprises layout data that includes geometric information related to the electronic design.

3. The method of claim 1 further comprising performing hierarchical analysis upon the incomplete design data to identify and organize relationships between instances and cells in the electronic design.

4. The method of claim 1 in which the model parameter extraction comprises geometry extraction that identifies relevant geometric characteristics and parameters of portions of the electronic design.

5. The method of claim 4 in which the relevant geometric characteristics and parameters of portions of the electronic design comprises perimeter, density, and line width information.

6. The method of claim 1 in which the results data is extracted for each instance in the electronic design.

7. The method of claim 1 in which the results data is updated based upon modification made by the designer to portions of the electronic design, wherein the results data with updates can be used by a second designer to perform predictions.

8. The method of claim 1 applied to either engineering change orders (ECO) or design planning.

9. The method of claim 1 in which the prediction comprises CMP, lithography, etch, or electrical predictions.

10. The method of claim 1 in which the predictions are performed only for a portion of the electronic design that has changed.

11. The method of claim 1 in which estimation is performed for one or more portions of the electronic design for which there is insufficient geometric information.

12. The method of claim 1 in which the results data comprises combined information from separate design files or databases from users that do not have access to the design files or the databases operated by other users.

13. A computer program product embodied on a non-transitory computer usable storage medium, the non-transitory computer readable storage medium having stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a method for performing analysis upon an electronic design, the method comprising:

receiving incomplete design data for an electronic design, which includes an incomplete electronic component design that is to be created in the electronic design, and information related to one or more models corresponding to a manufacturing process to be applied to manufacture the electronic design;

using a computer processor to perform model parameter determination for at least the incomplete electronic component design to generate a set of results data, wherein

the set of results data comprises simplification of one or more geometries that are not yet created for the incomplete design data rather than all geometric information of the one or more geometries; and

performing predictions of manufacturing effects for the electronic design for the manufacturing process before creation of the incomplete electronic component design, wherein

14. The computer program product of claim 13 in which the incomplete design data comprises layout data that includes geometric information related to the electronic design.

15. The computer program product of claim 13 further comprising performing hierarchical analysis upon the incomplete design data to identify and organize relationships between instances and cells in the electronic design.

16. The computer program product of claim 13 in which the model parameter extraction comprises geometry extraction that identifies relevant geometric characteristics and parameters of portions of the electronic design.

17. The computer program product of claim 16 in which the relevant geometric characteristics and parameters of portions of the electronic design comprises perimeter, density, and line width information.
