What tools are you using for your simulations? What hardware description language are you using? Do you have any plans to open source your hardware description? I wrote the simulator myself. Currently I am finishing a rework to support macros, including those defined on the schematics for D1, D2, D1R, DL, L, FF1, FF1, FF3, etc. Those circuits are currently only supported by gate level descriptions, so the macros will reduce the effort required to define a circuit. The simulator also supports exporting signals from one run to another, and defining time-dependent generators and switches. This makes to easy to run experiments on parts of a subsystem. When I'm satisfied that it is completely functional, if not entirely bug-free, I'll simply release the source and executables to anyone who wants them -- including the display program. Thanks for your interest. C.
