Finished sorting out pretty-printing in verbose mode, such that the messages logged by each Solve() process are filtered and printed collated and in-order at the end of each Tick(). Adding the mute…

Once we have more than one solution thread running at the same time the messages printed to the console during solution with m_verbose_flag = true all get jumbled-up. To be able to sort them so the…

Printing runtime messages straight to std::cout was fine until solving in multiple threads - The messages from the different threads end up co-mingled. Even if we pre-compose the message strings, t…

Revised folder structure. Componsed an elementary makefile to allow easier compilation of the demos.

Put together the really_long_inverter_chain to start trying to determine how big a device has to be before it's worth solving it in it's own thread. Found that deleting the Simulation took a *reall…

Finalised threaded solver. We can now set an optional argument in the Simulation class constructor, a struct comprising a boolean flag to turn on the threaded solver and an int that gives the nesti…

First draft of the game of life demo up and running. Every 18 ticks of the clock (9 true-false transitions) the cells change state. The cells are numbered row-wise, so if you change the dimensions …

Found a design flaw in the various binary counter models whereby I had improperly implemented the 'run' control input. I had missed the necessary first and gate out, so if the 0th flip-flop q = tru…

Re-worked the internals of the ram MagicDevice, it's now quite a bit quicker. Realised that using Probes slows things down quite a bit while doing this, as went from ~2600msec to write and read 12 …

Backing up changes. A number of small alterations didn't work in ways that eventually indicated that the order of solution did not proceed sensibly. We no-longer propagate Device in and out pins wi…

Fixed Component search so it runs from the top-level irrespective of the caller. Created a reset pins method that gets called over the whole component tree in the same way. Hopefully we can now del…

Finished initial prototype of destructors for all simulator objects with the exception of MagicEngines. At the moment all of the tidy-up logic is in each object's Purge***() method. To delete the o…

Continuing to build-towards having working destructors for all objects. So far we can cleanly 'Purge' and delete Components *Gates, Devices and Simulations*, which internally takes care of deleting…

Finally getting round to working on code for Component destructors. We can now search for a Component by full name to return a pointer to it, then we pass that pointer as an argument to it's paren…

Broke Stabilise() by removing the Initialise() call from Devices. Device out pins *need* to be propagated following initialisation. We achieve this by ensuring the pin.state_changed flag is set to …
Show description for 247d3ffcommittedSebastien SikoraInitialise() is now only a method of Gate(s). Realised that Devices don't need to be initialised in the same way. If any of their in pins are Set(), they will already be on the m_propagate_next lis…
Show description for 6224f08committedSebastien SikoraAttempt to make Device.Solve() safe to execute in a separate thread. Inside Solve(), Set() calls on Device out pins no longer directly call into the parent's AddToPropagateNext() method. Once we en…

More tweaks. Made further efforts to add build-time checks on as many methods as possible. When these checks fail errors are appended to the Simulations m_build_errors. This has made debugging a fa…
Show description for d307c9fcommittedSebastien SikoraRevised the way in which the 'connectedness' of pins is tracked and checked. Each pin struct now has a drive field {bool, bool}, which describes if there is a drive into the pin, and out of the pin…

Updated README.md and tidied up and corrected a few comments elsewhere. Implemented hidden_out_pins to allow me to reimplement the Device 'all_stop' output as a hidden out pin. Hidden out pins are …
