Deterministic Built-In Self-Test |
| 摘要 |
Various aspects of the disclosed technology relate to deterministic built-in self-test. A deterministic built-in self-test system comprises: a decompressor configured at least to decompress one of compressed test patterns stored on chip for a predetermined number of times; and a controller configured at least to output a control signal that inverts outputs of the decompressor at one or more scan shift clock cycles based on control data stored on chip, enabling the system to output the predetermined number of test patterns based on the one of compressed test patterns, wherein the one or more scan shift clock cycles are different for each of the predetermined number of test patterns. |

1. A system, comprising:
a decompressor configured at least to decompress one of compressed test patterns stored on chip for a predetermined number of times; and a controller configured at least to output a control signal that inverts outputs of the decompressor at one or more scan shift clock cycles based on control data stored on chip, enabling the system to output the predetermined number of test patterns based on the one of compressed test patterns, wherein the one or more scan shift clock cycles are different for each of the predetermined number of test patterns. |
