Make some calls private which were public before.
Eliminate functions which would be executed only once.
Make terminal reference functions in twoterm.h return const.
Clearly identify the use cases which need a non-const ref
to terminals.
|
| |
|
|
| |
Identified a number of code locations which could accept const
arguments.

The purpose here is to make clear what is actually done and to reduce
usage of calls to update.
|
| |
|
| |
This seems to be a compiler/standard library issues.

Parameters are now passed to the netlist core as strings. During netlist
creation they are evaluated as functions. This opens the path to
parameters on subdevice level.
Examples:
PARAM(device.XY, (1+2*0.005))
RES(R1, 2.05*RES_K(1)+1)
In addition the commit contains dead code removal.

- Fixed some clang lint warnings
- Removed dead code
- Experimental parser code to allow calculations in parameter value.
This already works for compiled netlists. These changes are
currently disabled. Updated pong netlist (and CRC/SHA) to work
with this new code.

- remove pthrow trampline as proposed by Vas.
- identify throwing code by adding noexcept(false)
- move "connected term" information to setup code.
- srcclean

|

- refactor error messages.
- Fix some drivers to cope with outputted added my the mame driver
for video and sound.
- Fix validation.

- Removed DUMMY_INPUT. NC (not connected) pins should now use NC_PIN.
If a NC_PIN is actually connected, an error will be logged and
validation will fail.
- Enabled "extended" validation. This will catch now if power terminals
are not connected.
- Added const and noexcept where appropriate.
- Removed dead code.
- Fixed the 7414 Schmitt-Trigger device to use nld_power_pins

- Devices ttlhigh and ttlhow are no longer automatically created.
- All logic input devices (e.g. TTL_INPUT, LOGIC_INPUT) now need to have
their power terminals (VCC, GND) connected. This opens the route
for more appropriate proxy devices but comes at a cost. If the
connections are omitted your circuit will not work as expected.
Example:
LOGIC_INPUT(I_SD0, 1, "AY8910PORT")
NET_C(VCC, I_SD0.VCC)
NET_C(GND, I_SD0.GND)
- Updated all netlists.
- Removed proxy information from terminal objects. This was replaced by
a lookup hash whose life-span does not exceed netlest setup.
These changes enable the removal of a number of hacks from the
source going forward.

- fixed a code in the netlist creation which caused multiple proxies
to be created for output->terminal connections. A nice side effect of
this fix is a performance increase ~9% for kidniki and ~4% for pong.
Speaking about pong ... maximum is 490%. Dice is running at
280 FPS/60 FPS = 466%, however without any analog emulation.
- Replaced NL_NOEXCEPT with noexcept. assert is now exception-free.
- cppcheck and lint fixes.
|
| |
|
|
|
|
| |
- move memory pool to netlist_state_t removing one static allocation.
- add memory allocation stats to verbose output
- nl_assert no longer throws, first step to remove NL_EXCEPT macro.

- Fix automatic header generation
- clang lint fixes.
- srcclean
- remove dead code

This commit is a first step towards using formulas in parameters, i.e.
MAINCLOCK(clock, 20 * 30)
The intention is to improve readability and scalability.
Since device registration already provides all necessary information
about parameters, the code to create an include file for all
devices has been improved. Long term, this will remove the need for
device specific header files.
In addition going forward devices will accept either no connections or
all specified connections, i.e.
TTL_7400_NAND(name, chip1.2, chip2.3)
or
TTL_7400_NAND(name)
NET_C(...)
NET_C(...)
This will allow to remove all duplicate definitions which are currently
necessary, i.e. TTL_7400_NAND/TTL_7400_GATE

- comment style migration continues.
- Fixed a two bugs in the truthtable ignore inputs code
- refactored the truthtable code a bit for better readability.
- updated netlist specific gitignore.
|
| |
|
|
|
| |
- switch to VS 2019 community and fix standalone build.
- more migration to C++ comment style.
- add some more doxygen markup.
|

|
|

Still not optimal, but better than what we had previously. No exception
logging comes closer.
|
| |
|
|
|
|
|
|
| |
- more const
- explicitly raise exceptions instead of leaving this to log.fatal()
- correct a number of cppcheck findings.
- dead code removal
- clang lint corrections, e.g. include order
|
| |
|
|
|
|
| |
- Separate code out into pmath.h and pstonum.h.
- Fix VC build error
- optimize pfmtlog.h a bit

Both compiling the core and the shaders with __float128 now work.
The support was added to be ready to deal with academic edge cases.
Performance drops to 10% of double - thus disabled by default.

Renamed cast member of the constants struct to magic to clearly identify
magic numbers.
Introduced nlconst struct inheriting from plib::constants<nl_fptype> to
make code better understandable.
|

The newly added RELTOL and VNTOL parameters implement Newton convergence
checks comparable following other SPICE implementations.
The ACCURACY solver parameter now is only used for convergence checks in
iterative solvers.
In addition, type safety was significantly improved and a lot of "magic"
numbers are identifiable now.

- fixed a bug in the parray constructor
- replaced NL_NOEXCEPT with noexcept where appropriate
|
| |
|
|
|
|
|
| |
- solver: align matrix population along the various solvers
- solver: delete dead code
- renamed nl_double to nl_fptype and use nl_fptype where previously
double has been used.
- renamed param_double_t to param_fp_t
|
| |
|
|
|
|
|
|
| |
- Removed code no longer used
- Add noexcept where appropriate
- split pparser.[c|h] into ppreprocessor and ptokenizer
- smaller optimizations, e.g. use of std::size_t
- fix lint warnings
|
| |
|
|
|
|
|
|
| |
- Added support for line markers to the preprocessor and parser.
- Added support for include processing to the preprocessor.
- Moved sources base type to plib to be used for preprocessor includes.
This enables to include e.g. from rom memory regions.
- Renamed some defines
|
| |
|
|
|

After the recent string of updates pongf performance increased again.
Also includes code maintenance and some fixes for the aligned memory
operations.
|
| |
|
| |
Also improve code readability.

- added NOLINT where needed
|
| |
|
|
|
| |
- lint warnings
- remove const on return types
|
| |
|
|

Removed the home-brew implementation pstreams and replaced those with
c++ streams.
|
| |
|
|
|
| |
- prepare move to c++ streams and later std::string
- fix more lint and clang pedantic warnings/errors
- fix some bugs
|
| |
|
|
|
|
| |
- remove a lot of c library use and instead use c++
- improved pstring compatibility to std::string
- prepare removal of pstream

- converted NL_MAX_LINK_RESOLVE_LOOPS into a netlist parameter.
- Reduced potential bit-rot.
- nltool -v --version now displays values of all compile time defines.
There are still far too many compile time defines. However, most of them
ensure and test future scalability.
|
| |
|
|
| |
All pstonum calls now need to specify if they want local locale
or the "classic" "C" locale.

This fixes an over simplification. Logic devices implicitly assumed that
GND/VDD actually is connected to GND(i.e. 0V). There is no immediate
benefit from this change. It is a preparation for the future
scalability. Now all power terminals (typically 7/14, 8/16) have to be
explicitly connected to the supply rails.
Also added a validation mode to the netlist core. This is not
intended for running, but solely to better indentify pins which
are not properly connected.
