Abstract: Placement and routing are two main parts of the physical design in IC design flow. To optimize the placement and improve the performance of routing, early routability analysis during the placement is indispensable. In this paper, a new non-slicing irregular partition algorithm is proposed. And based on it, a routability analysis model for mix-signal integrated circuits is introduced. Two experiments prove the high efficiency and accuracy of this routability analysis method.
