"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) " - Differentiable-timing-driven global placement
