fx3 ibis model
is there an IBIS model for FX3 slave port pins (CLK, DATA32b, CTL). I am designing and fpga+fx3 board. All my traces have the same length(4.5cm /1.6 inch), same width (0.1mm/4mil) and they run on inner layers. I want to know if i still need the 22 ohm resistors that are in series to those pins on the development board. The VIO of the slave port is connected to 1.8V power supply.
