io_pin testing in FPGA Posted February 27, 2020 Hello All, I am using zynq 7000 customize board.In that a pin which is on bank 35 (FPGA) is taken on connector(j3).J3 connector is 7 pin connector in which 7 no. pin is ground. I am testing all io's by writing counter code. I am getting waveforms on DSO for all pins except 6 no. pin. I have added then chipscope .On chipscope i am getting the waveform but not on DSO. What can be the reason ?
