This program generates visual plans from the descriptions
contained in AstroChip files. AstroChip is a freeware
language for developing and testing chips.
The version 1.1 displays the same chips as version 1.0,
but it is possible to save and load displayed
integrated circuit plans, move objects like ANDs, ORs
and modules in the frame and resize modules. So you
can reduce the size of the unoptimized plans. Finding
an optimal arrangement of the elements is impossible
for large plans, because the algorithms for that task
are very slow even for the fastest computers on earth.
AstroChipLayoutDB1.1 does not allow moving the flipflops
near the module input. All other objects can be moved.
It is possible that an object selected for moving can't
be layed down anywhere, because the object can't be
connected anymore. The reason is that for connecting
not every path is checked because of performance reasons
and the path used the last time is also not found, because
the order of the creation of the paths has changed so
the situation is different. This is the biggest weakness
of this program, but this error occures not often.
You can save more often.
If something is changed in one module it is automatically
changed in all modules of the same type.
It took six days to extend the source from version
1.0 to version 1.1.
After entering the chip source and compiling the
source the visual result is created after using
the "view" button. Small chips appear immediately,
big ones (more than 1MB source) take a long time.
Use the console window for checking if there still is
progress. If the chip is displayed you can move it
with the cursor keys and get the file and move menu
by clicking anywhere or on an object.
