Lattice Radiant: What does DOPAD_DEL on Timing analyzer report means?
The DOPAD_DEL is the delay from the PADDO port to the IOPAD signal switching rail to rail and measured at mid point.
It is dependent on several factors such as :
1. The drive strength : 8ma default
2. The slew rate.
Note: As #1 and #2 increases, the delay decreases.
