The dilemma and solving ways of safety engineering practice base on large-scale engineering
Practice teaching is a key process of undergraduate education of safety engineering,and it is the only way to increase the theory and practice comprehensive ability.Practice base is the platform of practice teaching,and the construction of it plays a vital role on the effect of practice teaching.With the great engineering education concept as the guidance,according to the characteristics of safety engineering,based on analyzing the problem of current undergraduate education of safety engineering,a suggestion which supposed to construct a appropriate practice base to adapt the safety engineering undergraduate education of great engineering education was provided,by using the philosophy of abroad great engineering education concept.It aimed to improve the comprehensive,engineering practice ability,and evolve the thinking and innovative ability of the students.
Analog Intellectual Property Cores design is still under study [1, 2]. The precharacterized cell libraries concept cannot be applied because the devices (transistors, capacitors, resistors,...) are electrically sized regarding a specific context. Thus, the trend is to develop reusable generators. To guarantee a reusable and fast placement, slicing tree floorplan can be used. Considering a particular electrical sizing and a specific process, the analog devices may occupy a wide range of shapes because of folding. Finding the correct aspect ratio for each device which optimizes the placement under a specific height and/or width constraint may lead to examine a high number of cases. This paper presents a general placement method to manage rectangular objects with varying aspect ratio. This approach allows hierarchical layout-aware electrical sizing of analog circuits.
