We have ran Hier-RTLMP macro placer described in this [arXiv paper](https://arxiv.org/abs/2304.11761) on our modern benchmarks. The results are as follows:
-**Ariane133-NG45-68%-1.3ns**: Following table and screenshots shows the macro placement result of Ariane133 on NG45, generated using Hier-RTLMP.
