Hi everyone,

I need copy some design files (just schematic and symbol part) from 45nm process library to 15nm process library because I am interested in the comparison between them. Basic cells (NAND, XOR etc.) satisfying new size are given with the same library name. Then I moved high level files to the new directory. But when I opened new schematic in the new library, I found that the coordinate position of instances(just Basic Cells) are all changed a little bit while wire and pins are still there. So the ports of instances and corresponding wires are staggered. I need move those instances to the right position manually. But when the circuit is big it will be too much trouble. Then what should I do?

Thanks in advance!
Wayne
