****************************************************** Hello <!channel>. I would like to highlight two updates related to MPW-3. First, if you are using OpenLane to harden your project or sub macros, please update your OpenLane repo and rerun your project to ensure you have picked up the latest updates to the flow. The recommend tag is

mpw-3a

at https://github.com/efabless/OpenLane. OpenLane has been updated to address a timing violation issue identified from MPW-1. This change was related to an issue correctly with respect to RC extraction and identifying timing violations after layout. A change was also made to improve clock tree synthesis. Second, the submission process on the platform has been updated to include submitting a tapeout job to create your final project layout (after completing a successful precheck). This job run the final steps to integrate your design with the golden copy of Caravel, runs fill generation, adds a seal ring, and runs final metal density checks for the layout. You need to have successfully completed this step prior to the submission deadline. You can find the ‘Submit Tapeout’ button right next to the button for MPW precheck on your project ‘Workspace’ tab. We will post further instructions on how to correct any errors resulting tapeout. Thanks! *******************************************************

Hi @User, thanks for the update. I have a question about what happens when we hit that 'submit tapeout button'. Can we make updates to the design after that? I'm asking because in the past many people have made updates after the official deadline.

Just a heads up - the tag was just updated to

mpw-3a

that picks up an additional change for OpenLane related to timing analysis.
