FLIT: (F)PhotoLITography optics simulation application

About

This is FLIT - (F)PhotoLITography optics simulation application. This program is simulate a propogation of light waves in photolithograph. Program have GUI and computation as separate parts. GUI is writed in python for GTK2 widget set, and main part is writen in C. Mask is described by a vector file, that is rasterized with required resollution.

Status

Currently application working ONLY IN LINUX enviroment. It doesn't have installer, have bugs, etc, but it worked. It REALY compute a diffraction pattern of light in photolithography device. Image of the mask pattern projected into a destination using short length ligth waves. All parameters can be changed.

Although application currently run only on linux, the porting is actually very easy. C part probably should compile on MinGW or cygwin after some small changes, or even without them. Mail me if you have some serious intention using it on windows.

Downloads&Licensing

Install

First stage: Binary install

Download compled package from this site ( see Downloads section).

Program uses pygtk (for GTK2) and pygtk-libglade modules. Install it from you distribution. After you have it installed - just unpack archive.

First stage: Source install

Download&Unpack source distribution. To compile application you need standart gcc C enviroment. For GUI you need pygtk (for GTK2) and pygtk-libglade modules, install it from you distribution. Then do:

cd flit;cd modules

make all-drv

Second stage: Install support applications

Flit needs to work some free software:

gnuplot - Scientific data visualisation program. Present in virtually any general-purpose linux distribution.
skencil (sketch) - vector drawing program. You can download it from
http://www.skencil.org/ . (It writed in python.).

3st stage: set up parameters

Look at ${FLIT_ROOT}/modules/etc/flit.options and ${FLIT_ROOT}/modules/etc/options.flitgui . Set up path to sketch directory. It should be something like /usr/local/lib/skencil-0.6.16/

4st stage: Running

To run it just type

: ${FLIT_ROOT}/modules/flitgui1/flitgui1.py

Where ${FLIT_ROOT} is a place where FLIT is installed.

Documentation

In ${FLIT_ROOT}/doc/intel1.lyx you will find a LYX file with shot paper about used mathematics. Sorry, currently in russian only.

Also, you can find there descr.lyx - a small description of program parametes.

TODO and Plans

Included test (located in ${FLIT_ROOT}/modules/tests/perf ) indicate, that application is probably too slow for one single computer. So the cluster/other HPC solution is needed

cpu MHz : 870.388 model name : Pentium III (Coppermine) cache size : 256 KB

flitcomp_p2:DEBUG[38]: comp_main.c(main):163: End of program, EXIT 13.71 user, 0.21 system, 0:14.24 elapsed, 97% CPU

flitcomp_p3:DEBUG[38]: comp_main.c(main):163: End of program, EXIT 13.75 user, 0.21 system, 0:14.31 elapsed, 97% CPU

Future plans includes:

better documentation !!! :-)
Use some alternative methods to convert vector mask into raster: sodipody,inscape, ghostscript
some installer and static version of binares
SMP version (fork/thread )
MPI version
GRID version

Contribution&cooperation

We will be glad to cooperate with somene, who have access to appropriate photolitograph hardware, have scientific interests in the area, want to use FLIT in everyday work. If you can check this application on real data it would be great. Or give us some information about interfaces with EDA tools.
