ID:15539 VCO phase tap parameter <name> must be 0 when counter <name> uses cascade input for PLL "<name>"

CAUSE: The specified counter for the specified PLL is using its cascade input, but also has a non-zero VCO phase tap specified. When the counter uses its cascade input, the VCO phase tap must be 0.

ACTION: Set the VCO phase tap for the specified counter to 0, or modify the counter to not use the cascade input. If you want to use fine grain phase, specify fine grain phase only for the counter at the head of the counter cascade chain.
