Validation of software applied to virtual nuclear instruments

This article mainly introduces what virtual nuclear instrument is, the significance and necessity of validation procedures of software applied to virtual nuclear instrument, software verification and validation procedures, and the test strategy. We also combine with virtual multi-channel analysis system to introduce the test steps of applied software in detail. In general, the test used was divided into four steps as follows: unit test, integrated test, system test, validated test. In a word, the quality of software is life of nuclear instrument, however, how to improve the quality of software; strict validation is the most important aspect. (author)
