To enter Tcl commands, click in the command line entry box at the bottom of the Tcl Console, and type the commands.

Important: To get input from Tcl using the gets stdin command, you must launch the Vivado IDE from a command prompt, xterm, or Tcl shell. This ensures that the Vivado IDE does not hang while waiting for input. Alternatively, you can use the Vivado <version> Tcl Shell shortcut, and enter the start_gui command to open the Vivado IDE. When you use the gets stdin command from the Vivado IDE, the Vivado IDE reads the data entered in the command prompt, xterm, or Tcl shell.
