MPW-7 Project Resubmission Due December 5th
Jeff
Hello everyone,
We are happy to finally announce readiness to resubmit MPW-7 projects. We are asking all project owners who met the original submission deadline to resubmit their projects on the Efabless platform for MPW-7 by December 5th at 11:59 PST.
PROJECT RESUBMISSION
As part of resubmission, please complete the following steps:
Update your project to include verilog/rtl/user_defines.v .
Within this file, you will need to specify the power-on default configuration for each GPIO pad for your project
The configuration determines whether the pad is connected to the user or management area, digital vs analog, input vs output, and pull-up or pull-down resistors for inputs.
Please see the Section - GPIO Configuration 4 of the Caravel User Project documentation for further information.
You can find a copy of user_defines.v here. You need to modify the configuration for each IO based on your project’s IO usage.
Run chip-level static timing analysis for your project integrated in updated Caravel design.
Post-layout static timing analysis has been updated to catch the timing violations seen in MPW-2 silicon.
A new script has been created to run the updated timing analysis flow
Please see the documentation for how to run timing on existing projects ( or Step 4 of the Quickstart documentation for new projects ).
A summary of timing results is provided at the end of the flow.
If you identify a timing issue with your design - please post your issue on the Slack channel #timing-closure and we will provide guidance on options to address timing issues with Openlane.
Rerun mpw_precheck and tapeout on the Efabless platform for your MPW-7 project.
mpw_precheck includes an additional check to verify that user_defines.v has been properly provided for your project.
tapeout will include the updated Caravel design correcting issues found with MPW-2 silicon testing.
PROJECT SELECTION
Projects that complete resubmission by the deadline will be selected based using the lottery process based on their original submission date.
Thank you again for your continued patience, encouragement and support for this program.
