Cyclone IV EP4CE6E22C8N is not detecting in Quartus Programmer

Question

Hello,
I am trying to program Altera Cyclone IV EP4CE6E22C8N using USB blaster but device is not detecting.
JTAG ( TCK, TDO,  TDI, TMS) is connected well and having good continuity, checked using DMM.
Also all voltage levels are actual manner i.e
Vccio = 3.3V
Vint= 1.2V
Vaux= 2.5V
CE pin in connected to GND
Still not detecting.

I have another board with EP4CE10E22C8N which is working properly with USB blaster and Quartus programmer. New Board with new IC i.e EP4CE6E22C8N is not detecting.
Even I checked the waveforms on both boards, EP4CE10 is showing all JTAG waveforms but EP4CE6 is just showing JTAG Clock(TCK) what to do?
Please comment.
