Spartan-IIE FPGA Family: DC and Switching Characteristics
IOB Output Delay Adjustments for Different Standards(1)
Output delays terminating at a pad are specified for LVTTL with 12 mA drive and fast slew rate. For other standards, adjust
the delays by the values shown. A delay adjusted in this way constitutes a worst-case limit.
