The parameter variations should have certain spatial correlations during IC manufacturing process because all of devices are made from the common physical process. It is the closer the less for the spatial correlation of two devices. In analog-circuit layout automation, it is to determine the best layout placement of devices by considering spatial correlation and decide, in turn, the routing styles for improving the matching of desired parameters. In this thesis, two routing styles, via-less channel routing (VLCR) and balanced-via channel routing (BVCR), are proposed for completing the layout design. An example of array-type MiM capacitors is used to demonstrate the performance of the proposed channel router. In the experiment, the cases of different capacitance ratios in different segment units are considered and the evaluation of post-simulation is performed by SPICE conjunction with the parasitic parameter extractor Calibre. From the result, it is observed that routing might contribute extra up to 5 percent of mismatch after the placement determined. Routing results in the great effect on the desired performance.
