@manish03 can you attach screenshot of placement stage layout view?

manish03 commented 3 months ago

Hi, I have attached an image of the placement def. The run logs and defs are also uploaded on google drive. This link https://drive.google.com/file/d/1Rai2BjUs7r5tKEHdz4EyO71axhOrBqj1/view?usp=sharing is shared on invite only. This run is different from the one you have. Let me know if the die size is not able to have this design, causing congestion. Thanks, Manish

@manish03 I just checked your config.json. It is missing "FP_PDN_MACRO_HOOKS" definition. Refer https://openlane.readthedocs.io/en/latest/tutorials/openram.html this for configuration and how to integrate SRAM macros. Is it going for fab?

manish03 commented 3 months ago

Hi, I still have the routing Congestion. I am not sure of the utilization. From Synthesis report I get area as 2901153.668000 In the picture there is very little space left Can tiny tapeout be an option as. I can add more die as needed

@vijayank88 There is still a bug with OpenROAD for the GUI crashing. I will file a separate issue with OpenRAOD

@manish03 I viewed the layout using KLayout and indeed the design appears congested. There are macros at every corner and the standard cells are concentrated in the middle. Pins are also distributed at the corners which might prevent. You might want to change the pin placement and manually place the macros in better places such that the macro pins and design pins are easily accessible and don't cause congestion. You might also want to spread the standard cells a bit.
