Tips & Comments (and Bugs)

Windows 8.1  (and 10)

LASI should run on Windows 8.1 and 10 If they support Win32 programs. LASI is essentially an old-fashioned graphical workstation using a conventional mouse and keyboard running on a desktop or laptop.. Tiles and a touch screen are not well suited for multiple directories or precise graphics. 

Windows 7 (currently preferred)

Important:  When on Windows 7, if you notice anything unusual when running LASI that wasn't seen with XP such as error messages, crashes, hang-ups or extra redraws, first try setting the Compatibility Mode for Lasi7.exe to "Windows XP Service Pack 3". This also applies to 8.1 and probably 10.

When running Lasi7.exe press Ctrl-a. This will tell you the Compatibility setting.

To set Compatibility Mode go to the main \Lasi7 main folder and right-click an ".exe" file and then left-click "Properties". Click the "Compatibility" tab and choose Compatibility Mode "Windows XP Service Pack 3". For more information on Compatibility see Windows Help and Support

 Some things noticed on Windows 7:

  • Moving the cursor to a toolbar button so that a tooltip appears causes a redraw with some versions of Windows. This is probably because a part of the drawing area was erased by the tooltip and the system sends a repaint message to LASI. Under the Cnfg command check "Hide All Tooltips" to prevent it. Tooltips that are not very useful for LASI and can be disabled on version 7.0.92 while editing a drawing.

  • If you install the main program or any of the tutorial setups and you get a popup that the programs "might have not installed correctly", reinstall with the  the "recommended settings" option,

  • You might want to check or uncheck some of the graphic settings under Control Panel/System/Advanced System Settings/Performance/Visual Effects. Under Custom, setting "Use visual styles on windows and buttons" and "Smooth edges of screen fonts" and maybe a few other features can make running LASI on Windows 7 more agreeable. This requires a lot of "playing around". Avoid the "Animated" windows and Aero Peek.

  • On large layouts to make more resources available when running certain utility programs, LasiCkt or LasiDrc for example, it is a good idea to close the LASI editor and then reopen it after those programs have run. Start a utility from the LASI editor System mode, then close the editor. Run the utility and when the utility is finished, restart the editor.

  • Be sure to set the permissions for LASI Drawing Folder files to Full Control for your User. Without the permission to read, write, delete, etc. you will get error popups when running the editor and utilities.


  • If you are running XP try reducing the size of the Active Title Bar under display Properties/Appearance/Advanced. This seems to default to a size that is a bit large for LASI graphics.

  • If a UTILITY program's control panel chops off buttons or is generally the wrong size you can either resize it like any window, or you can reset it to the default size and position.  To do this move the utility control panel so that its upper-left corner is off-screen above or off-screen left. Close the program with the "X". When you restart the default size and position will be reset.

  • Try running Spice and Notepad.exe out of LASI with the Run button. Open and edit the CIR file with Notepad. You can change the variables and statements in the CIR file and then resimulate. If you change the layout or schematic however, you need to rerun LasiCkt, and you will probably have to close Spice.

  • Although we really didn't plan it that way, if you have your Windows File Types set properly with the target application as Lasi7.exe, you can just click on a TLC cell file and LASI will run with that cell. There is a drawback to this however. Since a TLC file is an XML text file you might want to read it as a text file and not start LASI.

  • If you are starting a layout without layers defined, you can Import layer definitions for various MOSIS processes from the TLD files in the \Lasi7\Resource folder.

  • Depending on your monitor, the orange color used for Connector Text in the layouts might need to be adjusted with Cnfg/Colors by changing the green to 160, 144 or 128 to make it stand out more over yellow.
