Virtual flat placement is the simultaneous placement of standard cells and macros for the whole chip

This placement is “virtual” because it temporarily considers the design to be entirely flat, without hierarchy. After you decide on the shapes and locations of the physical blocks, you restore the design hierarchy and proceed with the block-by-block physical design flow.
