The following 3 signals are selected to use the primary clock routing resources:
pll_clk (driver: U1_ddr_sdram_mem_top/U1_kbar_clk_pll/U1_PLL, clk load #: 816)
U1_ddr_sdram_mem_top/kbar_clk (driver: U1_ddr_sdram_mem_top/U1_kbar_clk_pll/U1_PLL, clk load #: 43)
clk_in_c (driver: clk_in, clk load #: 14)

The following 1 signal is selected to use the DCS clock routing resource:
clk_in_c (driver: clk_in, clk load #: 14)

The following 1 signal is selected to use the secondary clock routing resource:
rst_n_c (driver: rst_n, clk load #: 0, sr load #: 664, ce load #: 0)

WARNING - par: Secondary clock driver 'rst_n' is located at AB2 (not a
dedicated clock PIO). Please check if user already located this
comp, or this comp has dedicated connection with PLLs which must
be placed at its corresponding dedicated PIOs.
Signal rst_n_c is selected as Global Set/Reset.

Starting router resource preassignment
WARNING - par: The driver of secondary clock net rst_n_c is not placed on
one of the PIO sites which are dedicated for secondary clocks.
This secondary clock will be routed through general routing
resource and may suffer from excessive delay or skew.
Completed router resource preassignment. Real time: 1 mins 13 secs
Starting iterative routing.

For each routing iteration the number inside the parenthesis is the
total time (in picoseconds) the design is failing the timing constraints.
For each routing iteration the router will attempt to reduce this number
until the number of routing iterations is completed or the value is 0
meaning the design has fully met the timing constraints.
