Query: Net2: A Graph Attention Network Method Customized for Pre-Placement Net
  Length Estimation   Net length is a key proxy metric for optimizing timing and power across
various stages of a standard digital design flow. However, the bulk of net
length information is not available until cell placement, and hence it is a
significant challenge to explicitly consider net length optimization in design
stages prior to placement, such as logic synthesis. This work addresses this
challenge by proposing a graph attention network method with customization,
called Net2, to estimate individual net length before cell placement. Its
accuracy-oriented version Net2a achieves about 15% better accuracy than several
previous works in identifying both long nets and long critical paths. Its fast
version Net2f is more than 1000 times faster than placement while still
outperforms previous works and other neural network techniques in terms of
various accuracy metrics.
