4.1 Opening, Saving, and Creating New Source Code

Source code files are opened and saved using the Editor menu options. Any files that have been opened and modified in a source editor are automatically saved when you build a simulation.

Commands to Open an existing source code file:

•Double-click on the filename in the Project window,

•Or, choose the Editor > Open HDL file menu option,

•Or, choose a file name from the recently open file list at the bottom of the Editor menu.

Managing Editors During Single-Stepping:

•While stepping through the code, new editors will open in a new tab within the most recently active editor window.

•To move a tab to another tabbed window or the Report window, drag and drop the tab to that window.

•To open a tab in a new tabbed window, drag and drop the tab to a space outside any other tabbed window.

•Use the Window menu, to quickly move between different tabbed windows. Also the Alt-W-# will bring up the window quickly. Only the active tab's file name will be visible in this list.

•Also remember that double clicking in the Project window will bring up the relevant source code.

Create a new source code file:

•Select the Editor > New HDL file menu option to open the editor file and type in source code.

•Then right-click and choose Add to Project from the context menu to open a File Save As dialog.

•Pick an name for the file and save it to the project directory (or anywhere else that you want).

Saving files:

•Select the Editor > Save HDL file menu option to open a Save dialog. By default, Verilog file names have an extension of v, VHDL file names have an extension of vhd, and C++ files have an extension of cpp.

Close the editor window and save the source code:

•Select the Editor > Close menu option. If the file has been altered, you will be prompted to save the file.
