Holger Vogt 7130097710 Prevent crash when no simulation has been run and 
asking for plotting an event node
 2022-02-19 17:23:36 +01:00
Giles Atkinson 16f586b65e Respect the "tstart" parameter when saving event node data (XSPICE). 
Fixes Support Request #47: "XSpice memory usage (TRAN TSTART effect)".

Brian Taylor 08bc3ccdd6 Remove compiler warnings (writ_ifs.c ipcsockets.c). 2022-01-13 14:54:16 +01:00
Holger Vogt f0e9a35eb6 Add 'esave' command to save only specific event nodes. 
Add a prompt for esave/eprint/eprvcd.

Holger Vogt 9308c6b077 Reuse memory for queued events. 
Patch #109 - 2 provided by Giles Atkinson
 2022-01-03 22:11:03 +01:00
Holger Vogt 8263e2a4da The AD and DA hybrid XSPICE bridges consume a lot of 
memory (one state per time step added). Memory of
previous time steps is not recovered.

Patch #109 by Giles Atkinson reduces memory consumption
dramatically (> factor of 10).

Holger Vogt c895ca33f7 Pswitch: Fix a bug in resistance calculation when cntl_on < cntl_off 
Correct setting of parens
 2021-10-29 16:35:47 +02:00
Holger Vogt eee639d98d Rename the capacitor and inductor code models to capacitoric and inductoric 
8e4db9109 ("adms bsimbulk and bsimcmg implementation based on work from Robert Larice", 2020-12-17)
changed inptypelk.c, line 37 from strcmp to strcasecmp.
Thus Capacitor (model for C) and code model capacitor are no longer
distinguished. Model parsing for the code models fails.

These code models are used very infrequently, thus renaming them
is a valid fix.

caused by some preceding error.

Holger Vogt 6aac403ab0 XSPICE delay: add some more safeguards 2021-08-03 15:53:42 +02:00
Holger Vogt 028dd0ab88 Remove unused 
Add a delay of half a time step to reduce error
 2021-07-05 14:24:46 +02:00
Holger Vogt abc6eb56f3 Plausibility checking 
Enforce out=in when delay == 0
 2021-07-05 14:24:29 +02:00
Holger Vogt fbab9a0fe2 Add an analog delay source for transient simulation 
Internal circular memory of size tstop/tstep or user defined.
(aprox.) every tstep a value is stored.
Delay time in multiples of tstep, by control voltage or user defined.
Dc or ac sim will simply connect input to output.

Holger Vogt d45e95aa4c We no longer want to install cmpp or other XSPICE files. 
The manual describes making code models from inside
the ngspice build process, and that's what we support
right now.

Holger Vogt a5eac333bb Revert "When installing ngspice, do not install the headers"

Holger Vogt 3c354092ff Line endings from \r\n to \n 2021-01-02 19:06:58 +01:00
Holger Vogt 5a0d213fec When installing ngspice, do not install the headers 
(all *.h), nor install dlmain.c and cmpp. Nearly all
users are not interested in creating code models, it is
not documated, and a much better way to create (and test)
code models is from within the ngspice sources (as is
documented in the manual).

Holger Vogt 92c6ff26f5 add a flag 'LIMIT' to pwl code model. If set true, 
the output is kept constant at y[0] when x is less then
x[0], or at y[xmax] when x > xmax.
Default is FALSE, then the output beyond the x bounds is
extrapolated linearly, as usual up to now.
