Abstract :
The layout of integrated circuits involves placing devices in a chip and interconnecting the devices. These terms are named placement and routing. However, conventional algorithms on placement and routing emphasize the initial construction of layout. Little concern is put on changes in placement and routing when there is adjustment of the circuit. In this paper, a new algorithm on layout of digital IC is proposed. The method will save IC designers from re-designing IC layout due to changes in design requirement
