IDELAY_CTRL vs multiple idelay ctrl blocks Everything I find on here and via google says that one only needs to instantiate a single idelay_ctrl block and multiple iodelays and "the tool" (meaning the vivado router/bitstream phase) will automatically replicate delay controls as needed.

    The IDELAYCTRL module provides a reference clock input that allows internal circuitry to derive a voltage bias, independent of PVT (process, voltage, and temperature) variations, in order to define precise delay tap values for the associated IDELAYE2 and ODELAYE2 components.
