Add Power Ring above Core. Innovus

LucaQ

Hi,

I'm working on an ASIC that cointains pixels where each pixel has half area for Analog part and half Area for Digital part.

I would like to know if for the digital part is possible to create the power ring of each pixel above the core using Innovus instead of having around the core.

And also if you have any other suggestion on how to create the power planning for a Pixellated circuit in Innovus will be very useful.

Thank you

  • Hi Luca,

    you can use the add_rings command with a negative value for the offset, this will create the power rings above the core area. E.g.

    add_rings -layer "Metal5" -nets "VSS VDD" -spacing 0.3 -width 0.5 -offset -3.0
