That generally call routing grid, to match the pin std cell position.
Historically, the backend designer should align this grid function of the std cell, now the tool are generally able to analyze the std cell pins positions.
The magma router has a routing grid, as other routing tool, plus a sub-routing that is the forth of the routing grid to provide more routing possibility.
