### Package to package spacing

This constraint defines the minimum allowable distance between two packages with various orientations. The format of the constraint value is like "SS:EE:SE:ES", where SS stands for Side to Side, EE stands for Edge to Edge, SE stands for Side to Edge and ES stands for Edge to Side. Example constraint value may look like 10:12:20:21. Each of the distance values are captured in design unit. DRC will be reported if any two packages placed in a given orientation violates the constraint value. The constraint can be different for different type of packages, and hence a triangular matrix is used to represent constraints among different packages.
