Holger Vogt d165329dca Enable parsing of the G poly source with extra parameters (e.g. m=2) 
by just cutting them off.
FIXME: to be added later, probaly in the code model.

an OSDI device and remove a limit on node count.
Problem was reported by user Sam in ngspice-users.

Giles Atkinson fc76d4d63b Always check for GUI events during simulation, if any graphs exist. 
Previously this check was only made if an iplot window existed.
The 100W.sp example displayed frozen windows with X11-based plotting.

Holger Vogt 312ef68614 Enhance the search path for .spiceinit (spice.rc): 
- in the directory from where the netlist has been loaded
- in a user provided path read from environmental variable SPICE_USERINIT_DIR,
- in the current directory,
- in the the HOME directory,
- in the USERPROFILE directory. */
In shared ngspice the first line shall read
- in the directory Infile_Path received from the caller (sent before initialization)

Giles Atkinson 1d8bec8909 Do not include term.h and curses.h in terminal.c without checking that 
they exist.  Modern ncurses does not need curses.h to compile term.h
so that header has been removed.  Also make ncurses the last choice
when looking for tputs().

Giles Atkinson e858ca9465 When parsing a XSPICE string-valued model parameter, break only 
on a closing quote, string end or white space (if unquoted) and
unquoted ']' when parsing an array.  That allows generic value overrides
for GHDL models to pass through: "-gVar=value".  Previously, the string
was terminated on '='.  Also remove some dead and non-functional code.
 2025-01-27 07:28:52 +00:00
Giles Atkinson 350147a231 Improve checking of XSPICE model parameters and tidy code. 
Checking for null values moves from per-instance code to
per-device code, potentially removing duplicate error messages.
Limits on parameter values and sizes of array parameters that are
specified in the IFS files are now actually checked.
