2.2.2. MAX® 10 I/O Banks Performance

The performance of the I/O banks differs for different I/O standards and I/O bank types. You must ensure that the frequency you specified passes timing check in the Quartus® Prime software.

The low speed I/O banks have lower maximum frequency than other I/O banks because of longer propagation delays. However, the delays do not affect the timing parameters such as slew rate, rise time, and fall time.

For details about the location of the high speed and low speed I/O banks, refer to the device pinout files.
