* netlist: more code maintenance. (nw) couriersud2019-11-1615-474/+502
| | | | | | - refactor error messages. - Fix some drivers to cope with outputted added my the mame driver for video and sound. - Fix validation.
* netlist: maintenance and bug fixes, remove DUMMY_INPUT. [Couriersud] couriersud2019-11-1532-348/+245
| | | | | | | | | | - 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
* netlist: Proxy and power terminal hack removal. [Couriersud] couriersud2019-11-1413-107/+184
| | | | | | | | | | | | | | | | | | - 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.
* netlist: bug fix, code maintenance and performance improvement. (nw) couriersud2019-11-1315-88/+121
| | | | | | | | | - 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.
* netlist: code maintenance. (nw) couriersud2019-11-1318-227/+322
| | | | | | - 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.
* netlist: maintenance. (nw) couriersud2019-11-1128-294/+129
| | | | | | | - Fix automatic header generation - clang lint fixes. - srcclean - remove dead code
* netlist: first steps on the way to calculated parameters. [Couriersud] couriersud2019-11-1022-106/+382
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* netlist: code maintenance. (nw) couriersud2019-11-1023-396/+469
| | | | | | - more doxygen \file annotations - moved MAINCLOCK back to nl_base.h - remove some const from simple function parameters
* netlist: code maintenance and bug fixes. (nw) couriersud2019-11-0882-1881/+1889
| | | | | | | - 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.
* netlist: maintenance. (nw) couriersud2019-11-0816-202/+238
| | | | | - switch to VS 2019 community and fix standalone build. - more migration to C++ comment style. - add some more doxygen markup.
* netlist: code and documentation maintenance fixes. [Couriersud] couriersud2019-11-0720-500/+809
| | | | | | | | | - "nltool -c docheader" now scans sources and creates usage focussed doxy documentation for devices. Very early stage, but works. For an example, please see ne555 source. - Started migrating to pure C++, i.e. "//" comments. - Various documentation fixes. - Added cppcheck configuration to netlist/build - Some smaller code changes.
* netlist: Minor optimizations. (nw) couriersud2019-11-054-38/+40

* netlist: more consistent exception handling. (nw) couriersud2019-11-0516-48/+44
| | | | Still not optimal, but better than what we had previously. No exception logging comes closer.
* netlist: code maintenance. (nw) couriersud2019-11-0443-191/+263
| | | | | | | | - 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
* misc cleanup (nw) Vas Crabb2019-11-051-1/+1

* Fix invalid std::vector<> lookup in aviio.cpp npwoods2019-11-041-1/+2
| | | | | | | | | | | | | This fixes a case where: * m_soundbuf_samples == processedsamples * processedsamples > 0 * processedsamples * stream->channels() == m_soundbuf.size() In this scenario, the std::memmove() would do nothing (moving zero bytes), but the operator[] on the second parameter to std::memmove() overflows the array. This can be benign in optimized builds (because the third parameter to std::memmove() is 0), but on debugging builds this can cause an assert.
* netlist: code maintenance. (nw) couriersud2019-11-047-6/+2
| | | | | - leave a note that cstdlib is needed for getenv. - Remove commented out includes - make sure all headers are self - contained, i.e. compile
* Fix clang error: no member named 'getenv' in namespace 'std' (nw) AJR2019-11-031-0/+1
| | | | Library differences are the culprit once again.
* netlist: code maintenance. (nw) couriersud2019-11-0339-515/+557
| | | | | | - Separate code out into pmath.h and pstonum.h. - Fix VC build error - optimize pfmtlog.h a bit
* netlist: remove pragma once. (nw) couriersud2019-11-038-18/+0
| | | Only used inconsistently in the code. May as well go.
* netlist: Completed __float128 support. [Couriersud] couriersud2019-11-0319-57/+281
| | | | | | 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.
* netlist: fix regression, preliminary __float128 support. (nw) couriersud2019-11-0311-23/+172
| | | | | __float128 is a gnu extension delivering true 128 bit floating point support. Currently not supported by clang. In addition, the quadmath library needs to be linked. For the time being therefore disabled.
* netlist: improve readability. (nw) couriersud2019-11-0232-352/+355
| | | | | | | 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.
* netlist: add RELTOL/VNTOL solver parameters. Type safety. [Couriersud] couriersud2019-11-0244-437/+510
| | | | | | | | | 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.
* netlist: Support for float, double and long double solvers. [Couriersud] couriersud2019-11-0233-263/+364
| | | | | | | | | | | | | - Added new solver parameter FPTYPE. This determines in which floating point domain the linear system is solved. May be one of "FLOAT", "DOUBLE" or "LONGDOUBLE" - Added option "--fperr" to nltool. This enables floating point exceptions. This helps debugging the code under gdb. The purpose of this going forward is to have more choice in optimization. Non-dynamic systems should be just fine in the float domain. Dynamic systems (i.e. diodes, bjts, mosfets) should in general work with double. Certain edge cases may require long double resolution.
* netlist: code maintenance and bugfixes. (nw) couriersud2019-11-0111-192/+199
| | | | - fixed a bug in the parray constructor - replaced NL_NOEXCEPT with noexcept where appropriate
* netlist: convert constexpr constants into constexpr inline funcs. (nw) couriersud2019-11-013-17/+18
|
* netlist: further solver refactoring. (nw) couriersud2019-11-0111-260/+270
|
* It's C++14 where constexpr variables still aren't inlined, making ridiculous ↵ AJR2019-10-312-3/+3
| | | | workarounds like this necessary to fix builds (nw)
* netlist: fix clang warnings & srcclean. (nw) couriersud2019-10-315-17/+17
|
* netlist: Compile with float/double floating point. [Couriersud] couriersud2019-10-3112-221/+282
| | | | | | | | | | | Added ability to compile using float instead of double. Specifically the the solver as well as the infrastructure now can have their own floating point type. Currently this is only an academic exercise since numerically demanding circuits like kidniki only work with double/double support. Using float here is pushing numerical stability over the limits. The long term design goal is too have the matrix type (double/float) being a parameter.
* netlist: maintenance and simplifcation. (nw) couriersud2019-10-3147-647/+595
| | | | | | | - 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
* netlist: move solver stuff into separate namespace. (nw) couriersud2019-10-3115-444/+446
| | | | | - new namespace "solver" - minor ptime modifications
