Parameter
The incremental values for the settings are generally linear. For the exact delay associated with each setting, use the
latest version of the Quartus II software.
The first number is the minimum timing parameter for industrial devices. The second number is the minimum
timing parameter for commercial devices.
The first number applies to -3 speed grade EP2S15, EP2S30, EP2S60, and EP2S90 devices. The second number
applies to -3 speed grade EP2S130 and EP2S180 devices.
