Yes my power supply rail voltages are correct and most supplies derived from LDO except 3.3V and 0.9V...

Does Arria II EP2AGX45CU17C6N have any specific power sequencing…??

Can I power up VCC, VCCIO, VCCL_GXD, VCCH_GXB, VCCA first and after some time (adding ferrite filter component and) powering up VCCB, VCCA_PLL and VCCD_PLL voltage pins, along with initial supplies…??

I faced problem at second time power up ie. VCCB and VCC_PLL along with initial supplies…
