RUMBLE: An Incremental Timing-Driven Physical-Synthesis Optimization Algorithm
Physical synthesis tools are responsible for achieving timing closure. Starting with 130nm designs, multiple cycles are required to cross the chip, making latch placement critical...

On whitespace and stability in physical synthesis
In the context of physical synthesis, large-scale standard-cell placement algorithms must facilitate incremental changes to layout, both local and global. In particular, flexible ...

Timing-driven Steiner trees are (practically) free
Traditionally, rectilinear Steiner minimum trees (RSMT) are widely used for routing estimation in design optimizations like floorplanning and physical synthesis. Since it optimize...
