Are the PHASER_IN, PHASER_OUT, and PHY Control 7 series components supported outside of MIG designs?
Can the components be directly instantiated in a user design?
No, these 7 series components are only supported through a 7 series MIG generated design.These blocks are not documented for general use and must be used through MIG. MIG properly instantiates, programs, calibrates, and connects these block within a MIG PHY.
7 series MIG does support standalone PHY designs where customers create custom controllers to interface to the PHY. This usage of the PHASERs and PHY Control block is supported.
