Hello all, I am working on a ARM development board. I am modifting its system FPGA which controls the peripherals. A signal output from the fpga is now in the high impedance stete from the fpga and is pulled up with a
10k resistor. VCC is 3.3V. Another signal is pulled down to gnd using a 4.7K resistor. is it possible to drive these signals from the FPGA. if yes what is the necessary modifications to be done in the ucf file (about the drive strength, pad type etc). i tried with LVTTL,PULLEDUP,Drive strength 12. But the value didnot changed. I working with a Xilinx VirtexE FPGA. Please advice me on this issue. Sumesh- posted
