Gradualist and Case Experimental Design for Digital Clock Based on Pocket Laboratory

In order to the reform of digital circuit experiment course, this paper introduces gradualist and case experimental teaching mode based on the FPGA pocket laboratory platform with the teaching resourc and an students' characteristics. The course selects a complete practical project, the digital clock design as a classic case,which is divided into basic, comprehensive, design-type, expanding innovation four levels from shallow to deep.The project can easy split into nine small experiments,which takes the experiment as gradualist teaching mode.Through the training of this model, the students can gradually finish the tasks of these experiments step by step with rapid interesting and promoted ability. All the experiments has achieved good results,most of which are valuable.
