This technique is considered as the future trend of instrument technology. the virtual instrument is one of computer instrument systems and it is based on the hardware of computer. the function of virtual instrument is defined and designed by consumer. the virtual instrument is with virtual panel and the testing function is implemented by software. the traditional instrument implements data analyzing, data processing and data display by hardware circuit, but the virtual instrument implements those functions by computers. though the collection of signal is done by the actual probe, data collection board and the i / o of computer. the virtual logical analyzer is made by the technology of virtual instrument
所謂虛擬儀器，就是在以計算機為核心的硬體平臺上，其功能由用戶設計和定義，具有虛擬面板，其測試功能由測試軟體實現的一種計算機儀器系統。它將傳統儀器由硬體電路實現的數據分析、處理與顯示功能，改由功能強大的計算機來執行，而信號的採集，仍然利用實際的探針，數據採集板和計算機i / o系統相結合的思想。虛擬邏輯分析儀就是按照虛擬儀器思想設計而成的。 -

However, these two views are static. data flow modelling does not show the sequence of processing while logical data modelling does not indicate how the data changes with time
可是，這兩個觀點是靜態的；數據流程模型沒有說明工序發生的先後，而邏輯數據模型則沒有說明數據如何隨著時間而改變。
