Description

I've been trying to harden my SoC using openlane. I was successful in hardening all my macros, but the flow fails when I try to integrate the macros in the final design. The error output is:

Environment

This github repo https://github.com/jurevreca12/rvj1-caravel-soc/tree/develop contains the relevant code. To reproduce the issue run: make user_project_wrapper. Beware that the relevant code is in the develop branch, and not the main branch.

Reproduction Material

I am also attaching the openroad reproducible as a zip file (openroad_issue_reproducible.zip) in this issue.

Expected behavior

A successfully generated final gds of the design.

Logs

None

EDIT:

openroad_issue_reproducible.zip

vijayank88 commented 2 years ago

@jurevreca12 this is not a valid test case

jurevreca12 commented 2 years ago

Sorry, about that. I attached the correct openroad_issue_reproducible.zip now.

mattvenn commented 2 years ago

thanks for opening

vijayank88 commented 2 years ago

@jurevreca12 your macro placed outside die area. Screenshot from 2022-05-23 18-23-14

jurevreca12 commented 2 years ago

How do I get this view? I've been (literally) drawing this on a piece of paper...

vijayank88 commented 2 years ago

Use openroad -gui

mattvenn commented 2 years ago

or look at the floorplan def file

The error shown in the report is "[ERROR]: /home/jure/Projekti/rvj1-caravel-soc/openlane/user_project_wrapper/../../gds/wbuart_wrap.gds doesn't exist." which doesn't seem to have anything to do with the title of this issue.

jurevreca12 commented 2 years ago

@maliberty ah yes. I've compressed the repo and then ran again to get the message. I'll fix this.

jurevreca12 commented 2 years ago

@vijayank88 Thank you for the help. This fixed my issue.

vijayank88 commented 2 years ago

@jurevreca12 If fixed, close this issue. Open new issue if you're facing any other issue again. Thanks.
