51b361bbf0
When Cider models are present, a normal batch mode sp_shutdown (for example, ngspice -b cmosinv.cir) will call com_quit(NULL). This cleans up so that valgrind will find no leaks in Cider devices after sp_shutdown. To disable this feature, set the environment variable CIDER_COM_QUIT="OFF". Even though it really does not matter that Cider memory is cleared just before exit, it makes it cleaner for valgrind checks.

Add inertial_delay=true to .model statements generated when U* instances in PSpice library subckts are translated to Xspice. Any other Xspice A* digital instances might have different inertial_delay settings in their models, so potentially there could be a mixture of delay types.

For unspecified gate delays (logic and tristate gates), which PSpice would consider as zero, set the rise and fall delays to 1.e-12s (the minimum for Xspice). For dff, jkff, dlatch, and srlatch use the Xspice default 1.0ns for rise and fall delays. If the ngspice variable (ps_port_directions & 2) is true, write the translated subckt to stdout, with TRANS_OUT prefix, for debugging purposes. The user could edit and replace the translated subckt if desired.

prototype for Verilog-A integration using OSDI and OpenVAF
...
This initial prototype is capable of performing DC, transient and AC
analysis. Not all features of OSDI are supported yet and there are still
some open questions regarding ngspice integration. However many usecase
already work very well and a large amount of CMC models are supported.
The biggest missing feature right now is noise analysis.

(testing) add res, cap and multiple devices test
feat: use osdi command to load files
Previously OSDI shared object files were loaded from fixed directories.
This was unreliable, inconvenient and caused conflicts with XSPICE.
This commit remove the old loading mechanism and instead introduces the
`osdi` command that can load (a list of) osdi object files (like the
codemodel command for XSPICE). A typical usecase will use this as a
precommand in the netlist:
.control
pre_osdi foo.osdi
.endc
If the specified file is a relative path it is first resolved relative
to the parent directory of the netlist. If the osdi command is invoked
from the interactive prompt the file is resolved relative to the current
working directory instead.
This commit also moves osdi from the devices folder to the root src
folder like xspice. This better reflects the role of the code as users
may otherthwise (mistakenly) assume that osdi is just another
handwritten model.

Consecutive tran and ac simulation may lead to gross errors
...
when TC or scale is used on the instance line of C and L.
Reason is the missing reset when CKTtemp is called once during each
simulation command. TC or scale is then applied again and again,
a reset is missing.
This patch adds a reset, i.e. the capacitance or inductance is
reset to its instance value in a call to *temp. It fixes bug#594.
Command 'alter' has been tested.
Resistance has not been tackled by this bug, because the line
here->RESconduct = here->RESm / (here->RESresist * factor * here->RESscale);
differs from
here->CAPcapac = here->CAPcapac * factor * here->CAPscale;
in that there is no accumulation of correction factors with here->RESconduct

Fix bugs found while investigating Bug #585 (convergence failure only

on Linux). In dctran.c make it impossible for a transient simulation
to run far past its end time and fix an infinite loop attempting to remove
the automatically-inserted ending breakpoint. In outitf.c fix memory
corruption if the simulation does over-run (change suggested by Holger Vogt).
