Hi, I tried to run grouping code on the [synthesized netlist](https://drive.google.com/file/d/1s5WmiV-8led7XijUospFF0LML9oQ88aL/view?usp=sharing) generated using the flow given in this [GitHub repo](https://github.com/TILOS-AI-Institute/MacroPlacement/tree/flow_scripts). I noticed grouper.py and hmetis_util.py uses gfile module to which...

Thank you for adding the grouping (clustering) library! With respect to "merge_small_adj_close_groups" ([line 598 of grouping.py](https://github.com/google-research/circuit_training/blob/05954b9be71768f0b1bc5ac3b3c610e39a89a852/circuit_training/grouping/grouping.py#L598)) and "breakup_groups" ([line 721](https://github.com/google-research/circuit_training/blob/05954b9be71768f0b1bc5ac3b3c610e39a89a852/circuit_training/grouping/grouping.py#L721)), could you please clarify how the incoming netlist has node...

Hi, Since TensorBoard.dev is shutting down, could you please export and share the TensorBoard details for the example Ariane runs provided [here](https://github.com/google-research/circuit_training/blob/main/docs/ARIANE.md#results)? Thanks, Sayak

Hi, After this [commit](https://github.com/google-research/circuit_training/commit/d5e454e5bcd153a95d320f664af0d1b378aace7b), I see the grouping code no longer supports two smaller split protobuf netlists as input as mentioned [here](https://github.com/google-research/circuit_training/tree/main/circuit_training/grouping#note). So I can not run the latest grouping...

### Description For one of our projects, we used OpenROAD and ran P&R for MegaBoom on Nangate45. We found that even after reducing the floorplan utilization to 20%, OpenROAD fails...

Library compiler errors out while generating the .db file from [asap7sc7p5t_SEQ_RVT_FF_nldm_201020.lib](https://github.com/The-OpenROAD-Project/asap7/blob/master/asap7sc7p5t_27/LIB/NLDM/asap7sc7p5t_SEQ_RVT_FF_nldm_201020.lib.gz). When I removed the ICG cells from the library the .db generation was successful. Is it possible to fix...

Question related to M5, M6 spacing?

In the Post-Route-Opt database of one of our internal design on ASAP7, we noticed lots of spacing DRC. After further analysis we found that for M6 the [minimum spacing](https://github.com/The-OpenROAD-Project/asap7/blob/cd13de4e603913291ec6b8401ab63ec481178a5a/asap7sc6t_26/techlef_misc/asap7sc6t_tech_4x_210831.lef#L543) requirement...
