Notes to Table 6–52:
(1) These timing parameters are sample-tested only.
(2) These timing parameters are for column IOE pins. Row IOE pins are 100- to 250-ps slower depending on device,
speed grade, and the specific parameter in question. You should use the Quartus II software to verify the external
timing for any pin.
Table 6–53 shows the external I/O timing parameters when using global
clock networks.
