Grid cell density is represented as an 1D array where the length is set to be the following:

- We do understand that Google has been working hard to complete the open-sourcing of Morpheus, and that this effort continues today. However, as pointed out in [this Doc](https://docs.google.com/document/d/1vkPRgJEiLIyT22AkQNAxO8JtIKiL95diVdJ_O4AFtJ8/edit?usp=sharing), it has been more than a year since "Data and Code Availability" was committed with publication of the [Nature paper](https://www.nature.com/articles/s41586-021-03544-w). We consider our work a "backstop" or "safety net" for Google's internal efforts, and a platform for researchers to build on.

**What is your timeline?**
- We hope to show significant progress at the [DAC-2022 Birds-of-a-Feather](https://59dac.conference-program.com/session/?sess=sess294) meeting (Open-Source EDA and Benchmarking Summit) on July 12, 2022, 7-10pm in Room 3000 of Moscone West in San Francisco.
