- OPENMP refactored. All OPENMP operations are now templatized in pomp.h
- We don't need thread-safe priority queue. Event code updating analog
outputs now runs outside the parallel code.

(nw) It doesn't work quite right yet. The "Hammer" and "Pest" sounds
are generated by free-running 555/556 timers and gated with LM324
applifiers. For whatever reason, the netlist system produces a kind of
buzzing from the "Hammer" circuit when it's supposed to be suppressed,
and it doesn't think the pest sound should be suppressed completely so
you can always hear it at a low level in the background. The "Cheese"
circuit is a bit weird - either they're using the base-emitter junction
of a 2SC945 as a signal diode, or there's an error in the schematic
(collector is shown unconnected). Connecting this part of the circuit
causes the netlist system to hang, so R2/R3/C8/Q2 are not connected for
now.
- more use of c++ features
- some CRTP in pfmtlog
- demangled code for truthtables
- use more constexpr
- rewrite main loop
- use default constructors and assignment operators were applicable.
- optimized 7448 and 9316
All of this has decreased startup time by approx. 25% to 30%. Complex
netlists like pong or kidniki are parsed, analyzed and constructed in
around 15 ms. Run performance has increased by about 5%.
All in all not to bad. A game like pong uses a clock of 7 MHz (after
division by 2). Thats 14 MHz clock invocations. Running at over 200%, 28
MHz. On a 3.9 GHz Machine about 140 cycles/clock change.

This removes all allocation code from pstring. const_iterator is
consequently now based on pstring::const_iterator.
Removed pstring_buffer. This was class wasn't a good idea.
Vas was right: This change did not impact runtime performance. Startup
performance (string intensive) increased. (nw)
Fixed -Winconsistent-missing-destructor-override warnings. Made
some constructors of template classes and classes with virtual .. = 0
methods protected. Fixed src/lib/netlist/build/makefile (nw)
Small improvement for 7493.
Convert 9316 from subdevice to delegate.
Convert 74107 from subdevice style to delegate.
Also refactored inconsistencies in other parts of the code. (nw)
... for updates. This will make device implementation more flexible and
faster. A nice side-effect is that there was some minor (<5%)
performance increase already. Each input is now assigned a notification
handler. Currently this is update, but going forward this may be a
custom handler. In addition
- fixed MEMPOOL on OSX
- removed dead code
- avoid bit-rot
- added delegate support for emscripten and arm processors
- added delegate support for VS 2015 x64
[Couriersud]
- Fixed crashes on terminals without nets (i.e. connected to a rail)
- Reviewed "FIXMEs" and corrected some minor ones.
- Made m_cur_analog protected.
- Fixed pmf delegates to work with msvc.
- More optimizations to the solver code.
- Started work on a better signal pipeline in nlwav
- Only generate documentation for entities which are documented.
[Couriersud]
Device implementations (all cpp files in netlist/devices) now should
only include nl_base.h.
Netlist implementation sources should only include "net_lib.h".
Refactored netlist.h and netlist.cpp to avoid namespace congestion in
netlist.h.
Fixed VC2015 build. (nw)
- Remove virtual from some destructors and make them protected.
- Various cleanups.
- Small performance improvement.
- Fixed some inconsistencies.
- More c++ refactoring. (nw)
Make streams provide binary access only. Use putf8_reader and
putf8_writer to actually access streams. Replace some char * parameters
with pstring where appropriate. Minor code refactoring and move
functionality were it belongs. (nw)
At the same time, any char pointer has to be explicitly converted to
pstring by specifying an encoding. Not yet optimal, but certainly better
than what was there before.
Removed unneeded methods from pstring. (nw)
- refactored reverse polish notation evaluator into own source files.
- added function parameter to current and voltage sources VS and CS.
You can now use those to e.g. produce a sine wave.
- Changed code to allow devices to optionally be treated as dynamic or
timestepping devices.
[Couriersud]
into these files as well. The code uses <cfenv> which is part of c++11
standard. Non-standard glib extensions are currently only used on linux
and (i386 or x86_64). (nw)
The identifier is used to load data from a source_t implementation. This
allos a consistent approach in netlists independent of netlist
implementation. Both sources code and parameter code needed quite some
rewrite to support this. [Couriersud]
-netlist: Added new devices: [Ryan Holtz]
* Intel 2102A 1Kbit (1024 x 1) Static RAM
* 74365 Hex Bus Driver with 3-State Outputs
* Generic 2- and 3-terminal Tristate device
* Note: Tristate device and 74365 do not actually tristate, they are simply a way of combining multiple outputs + chip enables.
Use macro NL_NOEXCEPT if debug builds would throw an exception (e.g. by
using nl_assert). This is not entirely safe. Going forward, nl_assert
should call log first and than throw. (nw)
- Removed trampolines (OUTLOGIC, INPLOGIC and friends).
- Started using doxygen comment and documentation style. Added doxygen
files to documentation folder.
- Refactored code triggered by doxygen output.
- Moved internal and support classes into namespace detail.
- Use an anordered map in parser.
- -Wconversion fixes - All done now.
- Fixed -Wold-style-cast warnings in netlist code.
- Added iterators to pstring.
- Moved two macros, added more RAII and improved exceptions. Fixed some
bugs in parser code.
- Fixed a number of bugs in parser code and exception handling.
[Couriersud]
- nltool now accepts -Ddefine=value to pass on to netlists
- improved option handling and added "dummy" options to add grouping and
examples in help output.
- improved --cmd=listdevices output
- Fix dynamic timestepping. This will work with breakout using real
capacitor modelling instead of delay devices. Really slow, but very
useful to calibrate timings.
- Fix an awful bug in timing for delay devices.
- Switched to clang 3.8 and made code compile with
-Weverything -Werror -Wno-old-style-cast -Wno-padded -Wno-weak-vtables
-Wno-missing-variable-declarations -Wno-conversion -Wno-c++98-compat
-Wno-float-equal -Wno-cast-align -Wno-global-constructors
-Wno-c++98-compat-pedantic -Wno-exit-time-destructors
-Wno-format-nonliteral -Wno-weak-template-vtables
This was a helpful exercise since it brought forward some
serious issues with implicit constructors.
[Couriersud]
- Replaced shared_ptr by unique_ptr.
- Better seperation of setup_t and netlist_t.
- Fixed bugs in rdtsc code. Refactored timer code.
- Simplify conditional activation/deactivation.
- Introduced HINT(device, hint) to clarify that hints are inheritent
and not specific to devices.
- Added improved profiling support to netlist. Statistics output now
proposes devices for which whole device activation/deactivation be
disabled. No significant improvement for pong, but breakout
experiences a 10% improvement.
- Moved options code from include to cpp file.
- Minor modifications to 7493 and 9316
- Introduced perftime_t and perfcount_t for gathering statistics. These
templates do not create any code if statistics are not kept.
- Make help2man ./nltool produce usuable output.
- More truthtable refactoring. Removed half-finished code for internal
state support. As implemented, this would have had no support for
timing delays.
[Couriersud]

Change UINT8 to uint_[fast|least|8_t.
Move state_var so it can be used by base devices as well.
Remove last traces of ATTR_ALIGN.
Refactored netlist_time into a template.
Removed implicit double assignment to netlist. Doomed to produce
bugs.
Instead, use netlist_time::from_double.
Switch to using proper (i.e. bool type) param_logic_t.
Formally differentiate between logic inputs (e.g. switches) and int
inputs (e.g. resistor ladders or selection switches).
Added parameter USE_DEACTIVATE to truthtable devices.
Added more constexpr to netlist_time.
Fixed some ifdef code paths.

- Use std::sort.
- Refactored netlist state manager.
- Introduction of state_var object template to be used on device
state
members.

Main use is in truthtable class.
- Remove PLIB_NAMESPACE macros.
- Remove namespace macros. Use explicit namespace declarations.
- Moved device definitions into cpp files.
- Moved more device definitions into cpp files.
- New prefix "nlid" for include files flags purely internal include
files not to be leaked into userland.
- Fix factory code.
Removed family_t. All of this can be determined at runtime from object
as well. As part of this, the "template" to write devices has changed.
Converted a number of devices to use the new template. [Couriersud]
- rename netlist_analog_t to analog_t
- straighten object model
- reduce access to member variables
- use pvector<analog_net_t::list_t> for groups.
- simple coverity fixes.
- First steps to move towards c++11.
