2.4 Reset Structure

The DEVICE_INIT_DONE, PLL Lock, and switch_i signals initiate the reset signal (FABRIC_RESET_N) from the CORERESET_PF_C0 block, which is synchronized with the OUT_FABCLK_0. The switch_i signal is connected to SW1 on the kit and this acts as external reset input to the design.

The following figure shows the reset structure of the demo design.
