You aim at some astonishing peak or a swerve of the river, then examine the screen on the back of your digital camera. A rogue, blurring tree has dived across like a goalkeeper to block your shot.

In designing synchronous digital integrated circuits, the design of clock tree is an important component, which may greatly affect the performance and reliability of the system.

This paper Introduces traditional method of fault tree analysis briefly. and discusses digital simulation method of mechanical fuse fault tree quantitative analysis.
