In ASIC design often used in bi-directional IO port to save the system s hardware resources. However, very few books on INOUT mouth design and simulation procedure is introduced, at the same time, a number of books to introduce the method in practice can not be used, the paper through an example of image sensor to a detailed description of the design method INOUT mouth and put forward some actual position in the simulation method
