## MaskPlace: Fast Chip Placement via Reinforced  Visual Representation Learning

A new chip placement method based on visual representation learning.

### The placement process animation

Benchmark: Bigblue3

### Standard Cell Placement

Benchmark: Bigblue3\
Fix macros and use DREAMPlace (classic optimization-based method) to place standard cells.
