Abstract
The common objective of very large scale integration (VLSI) placement problem is to minimize the total wirelength, which is calculated by the total half-perimeter wirelength (HPWL). Since the HPWL is not differentiable, various differentiable wirelength approximation functions have been proposed in nonlinear programming placement methods. The VLSI placement problem is NP-hard, and many placement constraints on a chip must be considered. It is a great challenge to design efficient and effective algorithms for the VLSI placement problem, especially for handling designs with millions of objects. In this talk, from the view of mathematics methods, I will try to discuss the characteristics of VLSI placement problem, and introduce some of our work on this problem.
