Important Notice

• We have a limited number of Synopsys licenses. If you exit your session normally, the license might not be released and others will not be able to use synopsys. Additionally, sometimes vhdldbx continues to run after a person normally logs off of a system and could be able to fill the home directory partition, resulting in others in the class losing some of the files that they try to write. Please exit from your session using the command kill -9 -1.
• Some useful unix commands are posted at http://www.ece.uvic.ca/computing/commands.shtml.

Taking Simulation Snapshots

1. The Synopsys simulator allows you to save the simulation results in postscript format. You can print the results later and attach them to the report. Check the Synopsys tutorial to find out how to save the results.
2. Use the "Image Viewer" from the CDE Desktop applications. Right click on the mouse somewhere in the workspace and select the Applications -> Application Manager icon from the Desktop tool bar. Then select the Desktop_Apps group. There you will find the Image Viewer program. This program has a nice interface for taking snapshots of the screen or specific windows. It also allows for the snapshot to be saved in a variety of different formats.
3. Use "xfig" found on most SUN workstations.
4. Use "xv" found on most SUN workstations.
1. When you run xv, a new window will pop.
2. Click on the right mouse button.  Another window will pop up. Select grab from this window and set the time to 10. Click OK.
3. Come back to the vhdl debugger window that has your waveforms and wait till you hear a bell.  Drag the left mouse button and grab the window.
4. In the xv window you must save the waveform you just captured.  Choose the format you like (jpeg, eps, etc.).  Type the name of the file to save.
5. Use the "snapshot" program found on some of the SUN workstations.
6. You can also use the screen capture utility of Frame Maker (a unix editor). If you want to use the Frame Maker follow the steps below:
1. Run the simulator and keep the simulation output in the simulator window.
2. Open a Maker document (a new one or a previously saved one).
3. Ensure that the simulator window is not hidden behind any other window.
4. Select the menu option: File -> Utilities -> Capture. A capture dialog box appears, select a name for the picture and click on the Capture button.
5. The cursor will have the shape of "+". Move the cursor to one of the simulator corners, drag to the other corner then release the mouse. The picture will be saved.
6. Go to the Maker document and position the cursor to the place where you want to insert the picture. Select the menu option: File -> Import -> File. Then select the picture you already saved.
