Stratix External I/O Timing
These timing parameters are for both column IOE and row IOE pins. In
EP1S30 devices and above, you can decrease the t
FPLLCLK, but may get positive hold time in EP1S60 and EP1S80 devices.
You should use the Quartus II software to verify the external devices for
any pin.

and row pins for EP1S10 devices.
