I/O Glitches

I/O glitches can occur at power up or power down. The conditions that cause the glitches depend on the use of GPIO or HSIO in the system. The dependencies of VDD, VDDI, and VDDAUX to mitigate any glitches on the I/O interfaces are discussed in respective UG0726: PolarFire FPGA Board Design User Guide or PolarFire SoC FPGA Board Design Guidelines User Guide .
