Global placement exploiting soft 2D regularity

Cell placement is such a critical step for chip physical design that it needs many kinds of
efforts for improvement. Recently, designs with 2D processing element arrays have become
popular primarily due to their deep neural network computing applications. The 2D array
regularity is similar to but different from the regularity of conventional datapath designs. To
exploit the 2D array regularity, this work develops a new global placement technique built
upon RePlAce, the latest state-of-the-art placement framework. Experimental results from …

Global Placement Exploiting Soft 2D Regularity

D Fang, B Zhang, H Hu, W Li, B Yuan… - ACM Transactions on …, 2025 - dl.acm.org
Cell placement is a step of paramount importance in chip physical design and requests
relentless effort for continuous improvement. Recently, designs with two-dimensional (2D)
processing element arrays have become popular primarily due to their deep neural network
hardware applications. The 2D array regularity is similar to but different from the regularity of
conventional datapath designs. To exploit the 2D array regularity, this work develops a new
global placement technique, Placement of Arrays with SOft Regularity (PASOR), built upon …
