ASTROCHIPLAYOUTDB1.1 22.8.2010


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.
