Global Placement Exploiting Soft 2D Regularity
Year: 2024
Type: article
Abstract: 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 RePlAce, the state-of-the-art placement framework. Experimental results from various designs show that the proposed approach can reduce global routing wirelength by 11% and 6% compared to RePlAce and a previous work on datapath driven placement, respectively.
