The test programs have been assembled with TASM (Telemark Cross Assembler), 
a free assembler available for DOS and Linux.

A few Modelsim simulation scripts are included to assist in running the test
benches with that simulator. They are in the synthesis directory.
The scripts expect that Modelsim's current directory is the synthesis directory.
(you can change the working directory with 'File'->'change directory').
If you don't use Modelsim standalone but from within an IDE, there's a couple
of independent scripts to help you organize the test signals.

A CP/M port for a Cyclone 2 starter board will eventually be included as a demo. 
It is still incomplete (a lot of necessary files haven't yet been uploaded to 
SVN) and unfinished.
