* This was an over-aggressive optimization. Now prints an info and
recommends to comment out if appropriate.
|
| |
|
|
|
| |
* Add cd4053 to netlist.lua
* Recreated nld_devinc.h
|

|
|
|
| |
* This is an infrastructure change to enable better error reporting
including file/source and line numbers in the future

* Example: PARAM(Solver.Solver_0.METHOD, "GMRES")
* Will use the GMRES solver instead of the default MAT_CR solver.
* Same applies to all Solver parameters.
* Please use with care. If you change your netlist (e.g. using
frontiers) the allocation of nets to solvers and the number of solvers
may change. Thus this type of tweaking should only be used after the
netlist completely works.

* more handler alignment
* dead code removal
* remove update calls which do nothing
|
| |
|
|
|
| |
* Default nmos power pins to VCC and GND.
* MOS uses VDD/VSS - update gamemachine netlist.
|
| |
|
|
|
|
|
|
|
| |
* For truthtable cmos devices the power pin names will now be set
according to the logic family.
* Fix some issues for CD4538
* Change "already connected" warning to info level. Some ICs (CD4538)
connect pins internally to GND and the schematics again externally. This
will cause this info to be printed. The warning now is a lot more
verbose.

* palloc.h/pmatrix2d.h: Fix static_assert warnings at the origin.
* Rework hints to broaden their use and fix NC hint.
* 74377: use NC hint
* plists.h: Fix debugging in MSVC
* Include cleanup: Move everything not needed by netlists from
nl_setup.h into core/setup.h
* Fix some clang tidy warnings
* srcclean

* Logic and analogue outputs can now be flagged as "NC" (not connected).
* Example: "HINT(IC13.4, NC)".
* This will suppress info messages to be logged.
* The HINT must apply to an existing terminal. HINTs for non-existing
terminals are treated as fatal errors.
* Terminals and logic inputs not connected are still treated as
warnings. These need though and a proper fix.
|
| |
|
|
| |
* also simplifiy a return.
* document parameter value resolution.

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.

- 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

Factory elements can now pass additional parameters to device
constructors. This makes the design of interface objects like analog
callbacks easier.
The change also allowed to remove some "deep" calls into the core from
the MAME interface in netlist.h

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.

pongf now peaks at 589% compared to 570% before.
Amongst a number of improvements in nl_base.h, the 7493 was touched.
Also has some code cleanup and hopefully faster compilation due to
extern template declarations.

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.

This change will make it a lot easier to add enhanced functionality to
the factory infrastructure.
Using integral constants also improves linking stability.

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.

These tristate buffers natively support tristate outputs. For use cases
with fixed enable inputs the devices support a parameter
FORCE_TRISTATE_LOGIC which if being set to 1 makes the device behave
like a logic output.
Added additional syntax and consistency checks for tristate outputs.
Updated the example and added dip implementations including
documentation.

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.

Also remove dead code and dead comments.
|
| |
|
|
|
|
| |
This a big forward to allow reuse of code. Still a longer way to go
but the foundation there.
Also brings quite a number of simplifications and dead code removal.

on connecting two terminals already on the same net.
|
| |
|
| |
moving over to clang-tidy-11 and enabling more warnings.
|
| |
|
|
| |
Unknown parameters like Solver.ABCD now will cause a fatal error to
be generated.
|

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.

- pstream simplification

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.
