using the dedicated JTAG IOs for JTAG to my DUT

I'm using the VCU118, which has an on-board Digilent UST to JTAG (using an FTDI chip).

I want to be able to "talk" to my DUT through JTAG command using this interface (preferably using a FTDI to JTAG software). 

so I don't want to connect my JTAG wire(TDI/TCK/...) to some other IOs, but use existing the IOs. 

Any ideas how to do this ?

do I understand you want to be able to access the JTAG pins of the FPGA with your own code in the PL ? If so then BSCAN block and this post might be of help,
