Webthe global timing metrics that we try to optimize. Due to the indifferentiability of timing metrics, it is very difficult to directly optimize the global circuit timing. Instead, state-of-the-art gate placement algorithms adopt a technique called net weighting [5–12]. They assign a weight coefficient to each interconnect wire (i.e., net) Webinequalities make Lagrangian non-differentiable. Sub-gradient method [2] was used to update Lagrange mul-tipliers on the non-differentiable Lagrangian. This paper presents an approach toward the path-oriented timing-driven placement. We adopt a non-linear timing model to estimate the delay. For the problem of the nonlinear system, we propose a ...
