VHDL: How to print out variables' value?

[notooth]

Can anyone guide me print out value of an VHDL signed/unsigned variable to the screen in Vivado?

Assuming you mean in simulation:

Code: [Select]

            report "Sync count is " & integer'image(to_integer(sync_count));

Gives:

Note: Sync count is 106

If you want to write a value to the serial port let me know, and I'll paste some code here.

And if it is when running the code in an FPGA, you can use in-system debugging as explained in chapter 10 and over of this document
