Brian Taylor 492bb64d92 By default, use the shortest typical delay estimate. This makes the digi_74LS90_74LS42.cir testcase for bug641 behave almost the same as MicroCap 12. In ngspice and MicroCap, the only signal with a glitch is not_y8. The other not_* signals look the same. Setting ps_use_mntymx in .spiceinit will change the delay estimates. See the function set_u_devices_info in src/frontend/udevices.c for the various settings of ps_use_mntymx. 2023-09-09 23:22:06 +02:00
Holger Vogt ad23146544 Don't check continuously for autostop, only when option flag is set 
This speeds up simulations with simple device evaluation, but many
time stepps.

"stop when a<>b".

Brian Taylor e235fda42b For d0_eff, d0_gff timing models specify the 1.0e-12 minimum Xspice delay valuesrather than defaulting to 1ns. 2023-08-11 11:37:19 +02:00
Holger Vogt d4c54123d4 Revert "Add code in ivars.c to look for a SPICE_ROOT environment variable" 
This reverts commit 6b0ab44f1e.
 2023-08-06 16:27:33 +02:00
Giles Atkinson 6b0ab44f1e Add code in ivars.c to look for a SPICE_ROOT environment variable 
that gives the location of the ngspice installation.  That allows
binaries to be installed in a different directory to the one
compiled in.  The spinit startup file is made location-independent
by passing a variable giving the location of loadable modules,
so this fixes Bug #615 -
"spinit contains arch dependent paths, but is installed as noarch DATA".
 2023-07-31 14:29:23 +02:00
Giles Atkinson 84821a4cf5 Add support for including analog node changes in VCD file output, 
and an option to explicitly set the VCD timestep.  Correct the
output value for high-impedance nodes.
 2023-07-31 14:28:29 +02:00
Holger Vogt 3adfa89cfc Prevent crash when number of parameter dependencies increases beyond 
limit. Raise the limit from 100 to 200.
 2023-07-31 14:27:49 +02:00
Holger Vogt aa10f9344e Add variable "csnumprec" to allow setting the precision of vectors 
and variables as arguments to functions listet in manual chapter 17.5.
Default is 6, as has been standard up to now.
 2023-07-31 14:27:23 +02:00
Holger Vogt fe3222a118 Add an option nginfo to enable a status report during simulation 
(currently available only with MS Windows GUI version).
 2023-07-31 14:26:40 +02:00
Holger Vogt c66f9faaab Remove compiler warnings (VS2022) 2023-07-31 14:26:23 +02:00
Brian Taylor b79eca646b Prevent crashes in udevices.c when malformed U* instances are present. This would happen with incorrectly written U* gates, ff, latches which do not conform to the PSpice specs. Instead, ERROR messages are output which, hopefully, will help a user to debug their subckt. 2023-07-31 14:26:01 +02:00
Giles Atkinson 480e269102 Allow netlist lines to grow during parameter substitution, 
removing a 25-character limit on the size of string parameters.

Brian Taylor 4d8b105b86 Simplify expression nesting depth. 2023-07-15 11:34:09 +02:00
Giles Atkinson a60b7f5630 Fix sluggish output of the "Reference value" progress indicator on Linux 
after it switched from stderr to stdout (28a3413).  Add fflush().
 2023-07-15 11:31:03 +02:00
Giles Atkinson ac6487932b Make the returned status of the "shell" command available as interpreter 
variable "shellstatus".  Also change the default shell to /bin/sh
as csh is now rare.
 2023-07-15 11:30:48 +02:00
Giles Atkinson 1c1a53bac8 Set default colours for the button box in the X11 plot window that 
match the default dark background of the plot.
 2023-07-15 11:30:29 +02:00
Giles Atkinson 5114d6c2f4 Add an option to the iplot command: -d sets the number of simulation 
steps before the window is shown.  The value can be chosen to
limit rapid resizing when starting and that is used in the PLL examples.
 2023-07-15 11:29:32 +02:00
Giles Atkinson e5a931e537 Improve commands for vector scales. "setscale" can now change 
or clear the scale of an individual vector and "compose" can
explicitly create a vector from XSPICE event node history.
 2023-07-15 11:28:48 +02:00

Holger Vogt eda9cadbed The 'plot' command is not available in batch mode. 
Issue a warning and ignore it.
 2023-07-15 11:22:00 +02:00
Holger Vogt f5091bdc2d Make the error message a little more reasonable. 
Unfortunately the current setup does not easily allow naming
the offending command.

Holger Vogt c1db561373 No syntax check for title line 2023-07-15 11:19:31 +02:00
Holger Vogt 3420e66705 During syntax check: v,i sources need two nodes, 
and prevent crash upon buggy ac input.
 2023-07-15 11:18:09 +02:00
Holger Vogt 29c51c0d30 Bail out if {...} or '...' are missing around RHS of the equation. 
(...) may be possible, elsewhere additional {} are put around,
so we have {(...)}.
