In the current evolution of semiconductors, circuit size is getting smaller and smaller, so the change process will result in a mismatch on the element. If we take the mismatch of wire into consideration, the parasitic effects on the circuit become very complex. Then, the relevance between analog components and circuits will become a major difficulty of circuit design. Circuit design automation therefore becomes an integral part, which not only can enhance our understanding of the whole circuit, but also can be helpful to find the necessary information in complicated circuit. It speedups the operation to the point where the human brain can’t be and therefore reliable automated design can be an important key to our design efficiency.
For such problems, first of all we define a single series resistor element and square resistors. In its design, elements can enhance the degree of matching quality. And in the setting of such elements, we can use all of the layout space for wiring, so the spatial distribution of the degree of utilization is improved. But in one track routing method, resistance matching between interconnects is guaranteed. After that setting the reorder unit may further identify the appropriate routing rule under severe restrictions, thus making the area less without affecting the degree of matching and balanced. At the end, the completed GUI is a better tool for designers. After all, you can′t make bricks without straw.
