2023-07-31 14:30:13 +02:00
Giles Atkinson 4df2e69009 Fix Bug #629 - "XSPICE d_osc failures". The old code has been completely
replaced by a new design that is faster, more reliable and does not
usually insert analog breakpoints.
2023-07-31 14:29:36 +02:00
Giles Atkinson 4cc0ac846d Add an option for parameters to the xfer code model to be provided
in a Touchstone-format file instead of as a model parameter.
The change to mif_inp2.c allows the "table" parameter to be omitted.
2023-07-31 14:28:40 +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
Giles Atkinson 576f218945 Fix the NAND and NOR variants of XSPICE code model multi_input_pwl
and add an example of its use with the E-source NAND variant.
2023-07-31 14:25:40 +02:00
Giles Atkinson 3a260fd4d9 Fix Bug 584 - "XSPICE dac_bridge model shows incorrect output timing."
Remove reliance on exact breakpoint timing and tidy code.
2023-07-31 14:25:31 +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
Giles Atkinson d31568bd83 Add parsing and translation of the FREQ form of E-source devices,
integrated with the existing parsing of AND/NAND/OR/NOR forms (inpcom.c).
For the implementation, add a new analog XSPICE code model, xfer.
Add an example to examples/sp.
2023-07-15 11:15:08 +02:00
Giles Atkinson eeb912228a When creating a plot vector from XSPICE event history, add a
final point at the end of the vector, so that a plotted line
does not end at the last event, leaving an odd spike.
2023-07-15 11:13:19 +02:00
Giles Atkinson 9099a922fd Apply a patch from Aleksey Morozov to fix a bug that he identified
and reproduced.  It is the same as Bug #331 -
"XSpice skips digital output point" except that it applies to the
instance queue, not the event queue.
2023-07-15 11:12:31 +02:00
Holger Vogt 678a6582f6 A preliminary fix to reduce the amount of missing pulses considerably.
Probably not yet the final solution.
2023-05-27 10:40:32 +02:00
Giles Atkinson 5aa48cab0b Do not generate netlist lines that use non-existent libraries.
To support that, give global scope to  function inp_pathresolve()
in inpcom.c.  Update internal documentation (long comment).

Holger Vogt 062785319a When '.probe alli' is set, disable auto bridging and set a flag 2023-03-24 22:10:18 +01:00
Giles Atkinson 5197200fb3 Fix crash reported by Brian Taylor. If "source" is used after
analysis, the circuit is both deleted and destroyed. Beware of
double frees.
2023-03-22 14:30:18 +01:00
Giles Atkinson 98333ee89a Fix a memory leak reported by Brian Taylor that was introduced
by commit 4d8e17487b.

Giles Atkinson e25f8bd522 Add inertial delay to missed d_xnor and tidy blank lines in d_xor. 2023-03-22 14:29:03 +01:00
Giles Atkinson cecce5163e Inertial delay for remaining simple gates and buffers:
nand or xor open_c open_e, but not tristate.

Giles Atkinson db38d4ad54 Correct timing of transitions to UNKNOWN. 2023-03-22 14:28:37 +01:00
Giles Atkinson 4623a04615 Interim version of inertial delay for tristate buffer.
This does not handle three-way or mixed transitions.
2023-03-22 14:28:15 +01:00
Giles Atkinson e3b4df6a51 First group of digital code models with improved implementation
of inertial delay: buffer, inverter, and, nor.  Also adds
utility function cm_is_inertial(().
2023-03-22 14:27:54 +01:00
Giles Atkinson 2643e3b17f New code-model library functions cm_schedule_output() and cm_getvar().
To be used in the inertial delay code for digital code models.
2023-03-22 14:27:35 +01:00
Giles Atkinson c1659a64c3 Change output event setup in evtload.c so that, when making an event call
to a code model, there is no longer a reference to the value of the event
at the head of the free list.  That allows all such free lists (with the
same data type) to be combined, probably improving performance.
This is in preparation for full implementation of inertial delay for
digital nodes.
2023-03-22 14:27:19 +01:00
Giles Atkinson 2d0561f386 Allow string-valued parameters to XSPICE device models with no default.
The code model then sees the value NULL.  Needed for the "family"
parameter on logic models, used by automatic bridge insertion.
2023-03-22 14:27:06 +01:00
Giles Atkinson 06aa693852 A new fix for Bug #331: "XSpice skips digital output point".
The problem was caused by removing an output queue from the "modified"
list when it had been modified by processing one of its events.
2023-03-18 14:33:02 +01:00
Giles Atkinson 7457a2684b Revert "Fixes bug #331"
This reverts commit 6d9876229c, because
it was found to break examples/xspice/various/xspice_c3.cir
(see discussion in bug report for February 2023) and an alternative
fix is available.
