Schematics of the EVM and the Interface Card

C4 and C8 on SLVP184 adjust the output turnon ramp-up rate and propagation
delay time. Reducing the capacitance of C8 will increase the output ramp-up
speed, and decreasing the value of C4 will reduce the output turnon delay time
and increase the output ramp-up rate.
