7 Series IDELAY ODELAY cascade

Hello does anyone know if it is possible to go from an IBUF -> IDELAY -> ODELAY -> BUFG

 

I know it is possibly for IBUF -> IDELAY -> IDELAY -> BUFG but I am using all of the IDELAY's in the current bank and I need more delay then 1 IDELAY provides. 

 

The IBUF is on a MRCC pin, I would like to use the dedicated routing from the CC pin to the BUFG so hopefully keep the ODELAY in the same slice.

Unfortunately no I do not think that is possible, the ODELAY output is only meant to out to an IOB. There is no path back from the ODELAY to the BUFG. 

Thanks,

Sandy

Hello,

 

I am working on Kintex 7 FPGA. To icrease the Tap value from 32, Would it be possible to cascade the IDELYE2 modules together? I did it in vivado but facing problem during design implementation.
