The Vivado tool writes a log file, called vivado.log, and a journal file called vivado.jou into the directory from which Vivado was launched. The log file is a record of the Tcl commands run during the design session, and the messages returned by the tool as a result of those commands. The journal is a record of the Tcl commands run during the session that can be used as a starting point to create new Tcl scripts.
- Select the Tcl Console window tab and type the following:
- To exit Vivado, enter the
- Close the Tcl shell window on Windows.
- Examine the Vivado log (vivado.log) file.
On Windows, it might be easier to use the file browser to locate and open the log file. The location of the Vivado log and journal file will be the directory from which the Vivado tool was launched, or can be separately configured in the Windows desktop icon. You will configure this in Lab #2.
In this case, look for the log file at the following location:
<Extract_Dir>/Vivado_Tutorial/vivado.logNote: The vivado.log and vivado.jou can also be written to %APPDATA%\Xilinx\Vivado, or to your /home directory.Note: Notice the log file contains the history and results of all Tcl commands executed during the Vivado session.
- Examine the Vivado journal (vivado.jou) file.
On Windows, it might be easier to use the file browser. Look for the journal file at the following location:
Notice the journal file contains only the Tcl commands executed during the Vivado session, without the added details recorded in the log file. The journal file is often helpful when creating Tcl scripts from prior design sessions, as you will see in the next lab.
