- added support parameter FORCE_TRISTATE_LOGIC on mk28000
- add system device SYS_PULSE to generate pulse based on input changes
parameters are delay, pulse width, input polarity and output polarity
- add USE_SPEED_HACKS define to gtrak10 to enable the use of the above
Brings gtrak10 from 18% to 120%.
- Improved interlaced video support in fixfreq.cpp
Added two interlace modes: progressive and interlaced which can
be selected in machine configuration.
- more clang format work
- rename link to connection
- introduced typed aliases. This information may be used later to
rewrite netlists.
- added a three terminal base device
This will allow the analog code to be more easily comparable to
literature about MNA (Modal node analysis).
BJT code is now a lot better readable.
- fix doxygen consistency
- added an example for a cmos inverter based on NMOS/PMOS fets.
- TRUTHTABLE_START was renamed to TRUTH_TABLE

copyright owners. Much thanks for that Couriersud, the main creator
and contributor, but also to Jonathan Gevaryahu and Sergey Svishchev.
There are small remnants in machine/NL_*, specifially breakout, pong
doubles and rebound that are also copyrighted by the DICE team,
whoever that means. They're not critical since they only concern
these drivers and not an important core subsystem.

* Electronic circuits and base components like resistors or capacitors

* Add google test syntax compatible unit testing support. This is a very
limited subset of the google test framework and not intended ever to be
a replacement. Adding a dependency to google test for the functionality
required was considered to be an overkill.
* nltool -c tests runs unit tests if linked in. This is *not* the case
for the version of nltool compiled with TOOLS=1.
* Added unit tests for plib::pfunction.

The purpose of this ongoing exercise is to remove unnecessary
dependencies in header files. netlist implementations should only have
access to what they need. The same applies to device implementations.
Core stuff will be moved to the core subdirectory going forward.

Kidniki now achieves up to 910% when run with static solvers and with
nltool. That is significant better than the 860% we have seen
previously.
This increase is driven by using a global memory pool in the solver
code.
In addition the following refactoring and code maintenance work is
included. Please excuse the large commit, some of this took interfered
with other work and the detail development steps were ugly.
- gsl support: This commit adds pgsl.h which implements a very limited
number of the functionality of the gsl header described in the c++ core
guidelines.
- clang-tidy fixes
- A significant refactoring of palloc.h. Aligned hints were removed,
they added complexity without a significant performance gain. Vector
operations should better be done on special spans/views.
The code has been tested on linux with g++-7, g++-9, clang-11.
On Windows mingw-10 and VS2019, OSX clang-11.

Use a more condensed matrix format for go, gt and Id matrices.
In addition, optimize the static compilation code.
|
| |
|
|
|
|
| |
- more c++14, use enable_if_t instead of enable_if
- cleaned up the use of memory allocation arenas
- reduce MACRO usage, use std::conditional where possible

plists.h was splitted into plists.h, pmulti_threading.h and
ptimed_queue.h. In addition removed plists.h from a number of files it
wasn't used in.
Certain minor adjustment needed to be made for cuda toolkit 10.1 and
10.2.

Rom and prom devices now properly support tristate outputs. Native OC
output still on the todo list.
In addition this commit fixes a number of bugs around dealing with macro
level parameters and improves documentation by adding a parameter table.
Also srcclean.

During object creation netlist tracks the source files which provide
object creation. This is later used e.g. by nltool to create
documentation from source.

Thanks to Aaron Giles who made me think about a different approach.
This is a rewrite from scratch for rom devices. It uses a generic
template to implement rom devices which is used together with a
description struct to define a rom device. This leads to highly
efficient code since all information is available at compile time.
This is also a step forward to support tristate outputs. All rom devices
covered by this approach have tristate or open collector outputs and
thus all code changes to support tristate outputs can now be made
consistently in one file.
|
| |
|
|
|
|
|
|
|
|
| |
Code cleanup to better separate the following stages:
- parsing
- setup
- run
In addition preliminary native tristate support was added. Not yet
production ready, please don't use it.

- working macro level parameters
- simplified code significantly
- fixed a number of hidden issue
- dead code removal
It is now possible to define netlist level parameters using:
static NETLIST_START(chip)
DEFPARAM(parameter, 123)
RES(R1, $(@.parameter))
....
NETLIST_END()
NETLIST_START(main)
chip(X1)
PARAM(X1.parameter, 1000)
...
NETLIST_END()
This will pass on 1000 to R1 as a parameter.
"@." will resolve to the current namespace. In this case it is X1, thus
"X1.parameter. This is during parsing. During evalution, i.e. device
creation, $(X1.parameter) is evaluated to 1000.
This also means, that global parameters are possible and accessible ...
DEFPARAM(P, 234)
...
RES(R1, $(P))
or going forward
RES(R1, 1000)
CAP(C1, 1.0 / $(R1.R))
This opens up the path to more possibilities ...
static NETLIST_START(DM9456_DIP)
DEFPARAM(MODEL, "74XX")
DM9456_GATE(X1)
DM9456_GATE(X2)
PARAM(X1.MODEL, $(@.MODEL))
PARAM(X2.MODEL, $(@.MODEL))
...
NETLIST_END()
NETLIST_START(main)
DM9456_DIP(X1)
PARAM(X1.MODEL, "LS74XX")
...
NETLIST_END()
The code also has been prepared to allow something along the lines of
LIBENTRY_MODEL(DM74LS00_DIP, DM7400_DIP, "LS74XX")
to define a LS version on top of an DM7400_DIP bare TTL implementation.
This however will need more efforts to existing devices to honour some
timing adjustment in the model definition. It will already honour
different output specifications between LS series and bare TTL if
connected to analog components.

- nlwav: remove m_channels completely
- nltool: add more comments to static_solvers.cpp
- clang make: add -Wunused-private-field

nlwav now supports 16 and 32 bit integer format (wav16s, wav32s)
as well as 32 bit float format (wav32f).
The "wav" format is no longer supported.
Added support for high and low pass filtering the wav output.
Dynamic volume adjustment (use "-a 0")
--hpboost can suppress spikes at the beginning of the file (<10ms)
The addition of the float format simplifies debugging significantly
since it covers the whole dynamic format.
Added nlwav to the local VS 2019 build.

This commit simplifies the creation of static solvers. For this to
happen the following changes were made:
- nltool does no longer support the "-f netlist_file.cpp" option.
All parts of netlist which used the option now expect the file
to be specified after all other options.
Before: nltool -t 10 -f somenetlist.cpp
Now : nltool -t 10 somenetlist.cpp
- The static compile command now supports an "--output" option
to specify the file to be created and accepts multiple input
files. To be create the static solver file for MAME use the
script provided or:
./nltool --cmd static
--output=src/lib/netlist/generated/static_solvers.cpp
src/mame/audio/nl_*.cpp src/mame/machine/nl_*.cpp
- Updated documentation and examples provided by nltool --help

This commit introduces precompiled static solver code. Due to
additional optimizations the compiler can use because the detail
calculation steps for the solution are known e.g. the kidniki netlist
sees a 100% speed increase.
In all environments (windows/*nix/osx) the source for the static
solver code can be created using
bash src/lib/netlist/nl_create_mame_solvers.sh
This will create src/lib/netlist/generated/static_solvers.cpp which is
compiled into the mame binary.
The script is just a temporary workaround. The intention is that nltool
whill be able to create this file with one call.
There are other improvements in this commit speeding up the processing
of timestep and dynamic calculations.

Change color levels for williams2 hardware to better color display.
Output levels are computed in netlist. These levels are aligned to
LTspice modelling I did.
Also improved the modelling to do what the actual hardware for mysticm
did: Color decoding depends on W13..W11. These are actually flip screen
versions of V13..V11. Fixed treatment on Bit0 although not used by the
game code.
Added R,G,B gain and offset sliders for the williams2 hardware. MAME
only supports one setting for all channels. This is not good enough
to come close to video recordings found on youtube.
Minor changes to nltool to better measure time taken to run a
simulation.
