No detection of xc7z030-2fg484i

I am using zynq xc7z030-2fg484i in our design. Device is not detecting in cascaded Jtag mode.  I checked power on sequence, POR and voltage levels and its ramp times.

 

  1. The voltages are all with in the operating limits.
  2. Power on reset is proper ie. Por is asserting 100milli seconds after vcco power good .
  3. Voltage Ramps with in the range of 200micro seconds to 50 milli seconds observed 24 mill seconds.
  4. Configuration is in cascaded Jtag mode.     
    •   all the above 1,2,3&4 points are observations. but while dumping program in to FPGA (using vivado16.3) nothing is detecting in "hardware manager". 
    • please review the schematics and suggest if anything wrong...

Thanks and Regards
