The first connection you created connects the SYS_CLK1_IN_0_1
port (created at the beginning of the dr.bd.tcl
script) with the SYS_CLK0_IN
input port of the Simulation Clock and Reset Generator IP.
The SYS_CLK0
pin of the Simulation Clock and Reset Generator IP is then connected to the sys_clk0
pin of the NoC.
