2. REPORT DETAILS
-----------------
TIMING-20#1 Warning
Non-clocked latch
The latch sys_mngr/axi_state_reg[0]_LDC cannot be properly analyzed as its control pin sys_mngr/axi_state_reg[0]_LDC/G is not reached by a timing clock
Related violations: <none>
TIMING-20#2 Warning
Non-clocked latch
The latch sys_mngr/axi_state_reg[10]_LDC cannot be properly analyzed as its control pin sys_mngr/axi_state_reg[10]_LDC/G is not reached by a timing clock
Related violations: <none>
TIMING-20#3 Warning
Non-clocked latch
The latch sys_mngr/axi_state_reg[1]_LDC cannot be properly analyzed as its control pin sys_mngr/axi_state_reg[1]_LDC/G is not reached by a timing clock
Related violations: <none>
TIMING-20#4 Warning
Non-clocked latch
The latch sys_mngr/axi_state_reg[2]_LDC cannot be properly analyzed as its control pin sys_mngr/axi_state_reg[2]_LDC/G is not reached by a timing clock
Related violations: <none>
TIMING-30#1 Warning
Sub-optimal master source pin selection for generated clock
The generated clock clk_gen has a sub-optimal master source pin selection, timing can be pessimistic
Related violations: <none>
XDCH-2#1 Warning
Same min and max delay values on IO port
The same input delay of 1.000 ns has been defined on port 'uart_rx' relative to clock clk_gen for both max and min. Make sure this reflects the design intent.
set_input_delay -clock [get_clocks clk_gen] 1.000 [get_ports uart_rx]

Related violations: <none>
XDCH-2#2 Warning
Same min and max delay values on IO port
The same output delay of 1.000 ns has been defined on port 'uart_tx' relative to clock clk_gen for both max and min. Make sure this reflects the design intent.
set_output_delay -clock [get_clocks clk_gen] 1.000 [get_ports uart_tx]
