The Output window is a quick way to view the files generated upon linking, compiling, and other actions in the schematic workspace. By default this window is docked at the bottom of the tool. The output window displays all the error messages which would have occurred due to different user actions. During linking, compilation and target download if there are any issues, which include linking errors due to incomplete schematic, compilation issues, dxe not loaded or dxe not matching with expected target etc, all these are displayed in the output window.
The top right corner of the output window has a button which is used for clearing the contents of the output window, which will be enabled only when the output window is not empty.
