Cyclone IV EP4CE6E22C8N is not detecting in Quartus Programmer

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.
