Abstract:

The status data exchange in the simulation of sequential circuit is studied,the method of constructing virtual trigger unit is analyzed,and the problem of temporarily stored output status data from virtual storage units is resolved.Both theoretical analysis and confirmatory experiments were applied in the study.The work is helpful to the design of digital circuit experiment and improvement of teaching method based on virtual instruments,and also provides more potential applications of virtual instruments.

Key words: virtual instrument;sequential logic;simulation;status data
