Special Route not connecting to Power Rings

l4mbd4

Hi,

I'm a newbie and I'm working on a mixed-signal chip in Innovus. I've got a few analog LEF files that I've imported into my floorplan as macros.

My chip has got two power domains - VCC and VBAT.

One of the macro in the VBAT domain uses VBAT and GND as power rails.

On doing Special-Route, I've got a lot of minute power rails for the standard cells, as expected.

But, the VBAT power rails are not getting extended till the outer power rings. Only the GND rails are correctly getting extended till the outer power rings.

A screen shot is attached for reference.

Thanks for any help.

    I have been facing the same issue. Did you happen to find a fix?
