Abstract

An information input unit inputs functional configuration information representing a function of a device to be validated. A condition input unit inputs conditions concerning input / output sequence that is given to the device. A function generation unit generates a validation item function that fulfills all of the conditions based on the functional configuration information. An extraction unit extracts a combination of configuration elements that constitute the functional configuration information as a validation item based on the validation item function.

Description

technical field [0001] The present invention relates to a technique for generating verification items to create an input / output sequence called a test pattern. Background technique [0002] Conventionally, large scale integration (LSI) design requires performing a verification process to verify normal operation of the LSI, and to improve work efficiency by shortening design time. In particular, the verification process is an indispensable step in order to maintain the high quality of LSIs that require large scale, advanced functions, high speed, and low power consumption. [0003] During verification, a series of input / output sequences called test patterns are created. According to this input / output sequence, an input signal is supplied to the LSI, and it is confirmed whether the output signal of the LSI matches an expected value. In this way, it is possible to verify that a device is functioning as expected. However, there are numerous functional devices in an LSI. In t...
