Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.
- added MOSFET model. Currently capacitances are not modelled.
This is a 3-pin model (Bulk connected to Source) with provisions to
extend it to 4-pin at a later stage.
- Add a capacitor generic model which is charge conserving.
Switch netlist to use this model instead of constant capacity model.
- Start putting constants into a central place.
Please expect minor timing differences due to a different numerical
path.
The cmos inverter example illustrates the analog implementation of a
cmos inverter gate. These were used a lot back in the 70s/80s to
generate sinus waves. The model should also be able to better emulate
4066 analog switches.
The addition of a relatively simple capacitor model is planned at a
later stage.
Expect everything from the MOSFET model at the current stage. Wrong
results as well as convergence issues and crashes.
sound board, completing the tromba circuit
(nw) I'm not sure whether the model works properly or not, but in the
circuit where it's used, I don't think it can work properly with the
current TTL output model. A capacitor is charged by the Q output of a
74LS74 flipflop (U3A) until the voltage passes the Schmitt trigger's
threshold, causing it to reset the flipflop. However, the positive
trigger voltage of the Schmitt trigger is 1.6V, but our TTL output model
has a high output voltage of 1.0V (see nl_base.cpp:89). I realise the
simplified model of TTL logic with high impedance inputs and outputs
behaving as though thery're loaded is convenient and fast to simulate,
but it's not detailed enough for applications like this where
7400-series chips are used in analog circuitry. This is what held me up
last time I tried adding a netlist for this sound board.
- 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)
- Moved 9312 and 74279 to ttl macro library.
- Renamed TTL_9312_* to DM9312. This is more appropriate.
- Fixed a number of warnings from latest ubuntu clang-5.0.
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)
- 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.

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)
-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.
- 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]
- Dead code removal and minor refactoring.
- Simplify. Align naming with stl. Fix somed pedantic warnings.
- More STL compatability.
- Remove ATTR_HOT and ATTR_COLD. Refactored netlist_time.
- Fix long standing workaround which would ignore policy of change-only"
propagation.
- Rewrote for loops to use auto : semantics.
- Truthtable cleanup. (nw)
- Get rid of nl_math. Remove nl_util.h and moved contents to
plib/putil.h.
- Fix standalone build. Refactor ptypes.h.
[Couriersud]
allow in-place creation (for increased locality) of netlist classes.
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.
