How to auto-place standard cells using its own prBoundary?

Hello,

Using Virtuoso Layout GXL 6.1.8 and I'm trying to place hundreds of standard cells automatically. The standard cell has its own prBoundary as highlighted in yellow. The boundary passes through the center of the tap contact.

How can I place the cells with their own prBoundary? Like shown below. the cells should also flip to share the VDD and VSS line. I tried "Place" --> "Analog" --> "Automatic Placement...". But it used the outer boundary of the cell, and the cells were not even side by side, there were gaps between each cell.

You should use Virtuoso Custom Placer for this. See this RAK: Virtuoso Custom Digital Placement - Row-Based and Constraint-Based Standard Cell Placement
