Synthesis ran without any high importance warnings, but at the end of implementation I get three high severity warnings after I run the "Report Timing Summary":
USB_UART_RXD: Port with no Input Delay
USB_UART_TXD: Port with no Input Delay
ddr3_sdram_reset_n: Port with no Output Delay
I do not know how should I constrain these inputs and outputs.
(Note: My Arty environment is working ok (board files have been downloaded and installed). I already have ran some basic logic circuits in the ARTY board successfully. My problems started with this project that includes the Microblaze and the uart)
Attached are the snapshot of my block design (It is basically a copy of Adam Taylor's design) and a copy of the warnings I get.
Let me know if I need to do something about these warnings, and if so, how,

Hi,
I am implementing in Vivado the Arty's Microblaze based design that Adam Taylor posted on his website: http://adiuvoengineering.com/?p=626I
I am having problems with it:
