Brian Taylor e703bd9142 Add comment about ps_udevice_msgs variable. Set to 1 will print PSpice instance names and types which are not supported and are found when processing a subckt. 2022-10-07 13:48:37 +02:00
Brian Taylor e9855be595 If variable ps_port_directions >= 2, also show the translated Xspice statements. 2022-10-07 13:48:05 +02:00

Holger Vogt 0754ea7657 Make the Error message a Warning message, 
because ngspice may move on
 2022-10-07 13:38:20 +02:00
Holger Vogt 0af4932c6f Prevent a crash if (due to input error) the node_table is not available. 2022-10-07 13:37:57 +02:00
Holger Vogt 43c5ffaae8 Add special savecurrents options: 
options savecurrents_bsim3, savecurrents_bsim4, and savecurrents_mos1
will save all device currents as listed in chapts 31.6.1, .8 and .9
of the ngspice manual. Pure savecurrents will yield a subset of MOS1
currents, as seen before.
 2022-10-07 13:24:12 +02:00
Holger Vogt e6772f4e4e Prevent crash in gettok() and similar functions by checking for NULL

Holger Vogt 037293c81e Improved error message: more info on the bad set form 2022-10-07 13:22:43 +02:00
Holger Vogt 26c687b088 enable evtcheck_nodes.c for MS Visual Studio 2022-10-07 13:21:02 +02:00
Giles Atkinson a0357b3432 Remove search for "family" parameters on subcircuits in XSPICE 
automatic bridging support as string-valued parameter support is
not yet intgrated.
 2022-10-07 13:20:34 +02:00
Giles Atkinson 4115064fd5 Latest auto-bridge code from development branch. 2022-10-07 13:20:17 +02:00
Giles Atkinson b1341c8e30 Insert XSPICE bridging devices automatically when an analogue node 
has the same name as an XSPICE event node (including digital nodes).
The function Evtcheck_nodes() is replaced by a new version in its
own file.
 2022-10-07 13:19:59 +02:00
Holger Vogt 07bb809158 Iterations for op or dc may start with arguments 0 for ln(). 
To cope with this, and potential overflow in exp function,
some limits have been added.

Holger Vogt d39c60542d Enable power measurement for W switch 2022-10-07 13:18:51 +02:00
Holger Vogt fe8eb26aaf Replace end-of-line comment delimiter $ by ; 
So to make it independent from compatibility switch selection.
 2022-10-07 13:18:29 +02:00
Holger Vogt 79bb8edc90 Allow individual current measurements in switches or 
linear dependent sources.
 2022-10-07 13:18:15 +02:00
Holger Vogt f1eb8d3955 examples for .probe alli or .probe i(xx) 2022-10-07 13:17:55 +02:00
Holger Vogt 7e610c8487 .probe alli improved: 
* Enable current mesurement for I source
* Look at only the first 2 nodes of S and W switches
and F and G controlled current sources, measure current
with = voltage source added to second node. So we get
I(Fx), I(Gx), I(Sx), and I(Wx).

Holger Vogt a1dd1f5563 Check for tran at first when linearize is called. 2022-10-07 13:16:03 +02:00
Brian Taylor 3ca91aa1ac Make a trivial change to support (n)and3a, (n)or3a, (n)xor3a types. These are not used in any of the Micro Cap libraries. Completes support for Pspice tristate gate types. 2022-10-07 13:15:45 +02:00
Brian Taylor 4706c3dea5 Add 74xx283 4-bit adder example from the Micro Cap digital example circuits. Pspice primitives are translated to Xspice and a waveform is displayed using GTKWave. This is a digital-only test. 2022-10-07 13:15:23 +02:00
Brian Taylor abd4af1ae6 Ignore IO models in a subckt. Setting variable ps_port_directions to a non-zero int prints the directions (IN, OUT, INOUT) of subckt ports. 2022-10-07 13:14:58 +02:00
Brian Taylor 2d9f86c742 Check for name collisions between nodes generated during translation from Pspice to Xspice and instance pin or subckt port names. These are reported as ERRRORs. 2022-10-07 13:14:35 +02:00
Holger Vogt e9b5a9a957 aswitch needs two input nodes because gd has been selected for input. 2022-10-07 13:13:38 +02:00
Holger Vogt c8ed9590b7 Handle the case when control voltages on and off are equal. 
Update the linear switch: add the limits to resistance ron, roff
Update the log switch: correct the resistance calculation for
von < voff
Add some examples for the pswitch.
 2022-10-07 13:12:56 +02:00
Holger Vogt b94ef139dd Avoid an endless loop: Safeguard function 
search_plain_identifier(char *str, const char *identifier)
against identifiers being an empty string.
 2022-10-07 13:12:30 +02:00
Holger Vogt 5b0b328186 If a node name to be plotted ends by ':power', its type is set to POWER. 
Thus 'settype power nodename(s)' in the examples is no longer necessary.
 2022-10-07 13:12:04 +02:00
Holger Vogt fc0bf595f2 Update to .probe command: 
If no .save or save command given by the user, add '.save all' internally.
To do so, check for .save or save.
Update to the .probe p command (power measurement)
Add probe_int_ to internal nodes and instance names, where appropriate.
These nodes will be disregarded when setting up the plot structure.

Holger Vogt 2deefe1fbc New tables for MOS devices 2022-10-07 13:11:18 +02:00
Holger Vogt 765d2e8a0e Return data to input directory. 2022-10-07 13:10:51 +02:00
Holger Vogt 3da97fa277 Handle .if ... .else ... .endif before .csparam is executed, 
thus allowing parameter entry to .control section being dependent
on .if
 2022-10-07 13:10:31 +02:00
Holger Vogt a69dd1bcde Simplify the NMOS or PMOS selection by setting only one parameter 
'mostype'
ngspice-37+ is required.

Giles Atkinson 8038021369 Remove some dead code in the dec_bridge code model. 2022-10-07 13:09:36 +02:00
Giles Atkinson 88d5e723ed Fix double free in XSPICE CALLBACK functions as desribed here: 
https://sourceforge.net/p/ngspice/mailman/message/37677362/
and add missing CALLBACKs in models that use STATIC_VARs with
pointer values.
 2022-10-07 13:09:15 +02:00
Giles Atkinson 10d3e1b754 Extend the output and partial derivatives of the output from the 2/3-D 
table lookup models (XSPICE) continuously outside the defined
rectangle or cube, as it may help convergence and avoid ambiguity caused
by rounding at the boundaries.  See bug #591 "Wrong 2D table model output".
The value is that of the nearest point in the region while the reported
derivative is ramped to zero outside the boundaries.
Also fixes incorrect output at the upper limit in each dimension.
 2022-10-07 13:09:00 +02:00
Giles Atkinson 8ef2d8dec8 Fix memory leak by moving the state transition table to a STATIC_VAR 
whose memory can be recovered by a call back.  Also make cfunc.mod
less ugly.
 2022-10-07 13:08:42 +02:00
Holger Vogt 0e885bc3a9 Function guess_type may yield the wrong type, because 
it does not cover all of the the many, many options possible.
This commit fixes bug597, where [current] was interpreted as
capacitance.
 2022-10-07 13:06:29 +02:00
Holger Vogt 7f65a68ad6 Improve (a little) the plotting of digital data with plot option digiplot: 
Repair scaling on MS Windows:
Suppress y axis lettering and unit:
Allow or dis-allow grid.
 2022-10-07 13:05:56 +02:00
Holger Vogt 9e290a3461 tabs to spaces 2022-10-07 13:05:30 +02:00
Holger Vogt 8a097c020e Make error message more verbose: Instead of only "no such parameter on this device", 
give name of bad parameter and respective line in netlist.
 2022-10-07 13:05:10 +02:00
Holger Vogt 73ee9e452d Prevent crash when ca or d are not defined. May happen when 
.endc is missing.
 2022-10-07 13:04:50 +02:00
Holger Vogt b9014068e7 WinGUI: Add a button 'Stop' to stop a simulation in intercative 
or control mode. ngspice enters interactive mode and waits for user
commands. Simulation result vectors are available up to the
(time) point of stopping. Simulation may continue by command
'resume', however now in interactive mode, a control flow stays
interrupted.
 2022-10-07 13:04:25 +02:00
Holger Vogt 5cf6c23db8 Add udevices.c to project 2022-10-07 13:03:52 +02:00
Holger Vogt d1cbcb080c Re-format cktdojob.c 2022-10-07 13:03:35 +02:00
Holger Vogt 9e1eac0613 Correct comment: Command circbyline is not involved, 
we are sending the netlist as an array.
 2022-10-07 13:03:18 +02:00
Holger Vogt a597c6a295 Suppress I/O redirection for command 'circbyline'. 
This enables sending commands like
circbyline btest testnode 0 v=((v(in1) - v(in2)) < 0.1 ? 0.111 : v(in1))
