The circuitry that results from instantiating the IDELAYCTRL components as shown is
illustrated in
Instantiating Multiple IDELAYCTRLs without LOC Constraints
Instantiating multiple IDELAYCTRL instances without LOC properties is prohibited. If
this occurs, an error is issued by the implementation tools.
OLOGIC blocks include six storage elements (shown in
registers (TFF1, TFF2, and TFF3) are used for 3-state control. The bottom three registers
(OFF1, OFF2, and OFF3) are used for data output. Both sets of registers are functionally the
same.
