TEST PATTERN GENERATION SYSTEMS AND METHODS
First Claim
1. A test pattern generation system, comprising:
- test pattern generation circuitry, which, when in use;
receives a noise image;
generates a pattern image based on the noise image; and
generates a test pattern based on the pattern image, the test pattern being representative of geometric shapes of an electronic device design layout that is free of design rule check (DRC) violations.

Abstract
Systems and methods are provided for generating test patterns. In various embodiments, systems and methods are provided in which machine learning is utilized to generate the test patterns in a manner so that the test patterns conform with design rule check (DRC) specified for a particular semiconductor manufacturing process or for particular types of devices. A test pattern generation system includes test pattern generation circuitry which receives a noise image. The test pattern generation generates a pattern image based on the noise image, and further generates a test pattern based on the pattern image. The test pattern is representative of geometric shapes of an electronic device design layout that is free of design rule check violations.

13. A method, comprising:
-
training a discriminator of a test generation machine learning circuitry by; providing first training input representative of a first plurality of layout clips to the discriminator, the first plurality of layout clips being layout clips for electronic devices which are known to be free of design rule check (DRC) violations; and providing second training input representative of a second plurality of layout clips to the discriminator, the second plurality of layout clips being layout clips for electronic devices which are known to include one or more DRC violations; and modifying parameters of the discriminator based on the training, the discriminator being configured to classify a received input as being representative of a valid layout clip or an invalid layout clip based on the modified parameters. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
