Tips & Comments (and Bugs)
8 and 8.1 (and 10)
should run on Windows 8 but tiles and a touch screen are not well suited for multiple directories or precise graphics.
LASI is essentially an old-fashioned graphical work station. You still need a
MOUSE and a KEYBOARD. If
Lasi7.exe is run from a tile the LASI editor Startup dialog will usually
pop-up and you will have to browse to a LASI drawing folder. Windows 8.1 with a
should be preferred, or a 3rd party desktop add-on may also work. We
have not done much testing with this. Windows 10 due out in 2015 may be much
better since it should detect mouse and keyboard and have an optional
you have Vista or Windows 7, and if you notice anything unusual when
running LASI that
wasn't seen with XP, please let us know. We test LASI on 64-bit
Windows 7, but can't check everything. Although many people still use
XP they eventually will be on Windows 7 (or 8) if they get new
things noticed on Windows 7:
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, or just ignore the message.
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. Avoid the "Animated" windows and Aero Peek.
We have noticed that
when "Use visual styles on windows
and buttons" is set that when drawing a very large number of
partly finishes and then goes into a continuous redraw loop. This
occurs after another application has been opened ... and even after it
is closed. This does not seem to happen if Windows 7 "Use visual styles
on buttons and windows"
is turned off. Unfortunately when turned off this gives a classic
Windows 2000 style which is pretty much out of date. We are still investigating.
To stop this
draw loop, press SPACE and then Zoom
into a smaller drawing area where there are less objects to
draw. Putting large cells in outline using Outl also
reduces the objects to draw. Restarting the LASI editor clears the problem until
another application is run.
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.
using a non-Aero theme and a drawing redraws when a tooltip pops-up or closes,
check "Hide Tooltips" under Cnfg.
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 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
a text file you might want to read it as a text file and not
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.
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.
