  • b06275f045 Update example hv_rf_preliminary Holger Vogt 2026-08-14 18:20:53 +0200
  • a4ff5a204a Fixes bug 862 Break up OSDI initialisation in case of model or instance error. pre-master-48 Holger Vogt 2026-08-14 17:21:12 +0200
  • 300d01e0f8 Use 'arrowplot', and plot mag(vector) Holger Vogt 2026-08-14 14:30:12 +0200
  • bd395341d5 use the old 'xbrushwidth' lable as an alternative to 'pyplot_linewidth' Holger Vogt 2026-08-14 11:48:38 +0200
  • c93b0ec179 Use arrowplot (vertical lines or arrows at frequency of interest). Holger Vogt 2026-08-14 11:40:05 +0200
  • af60e41db4 enable arrowplot (not yet arrows, but vertical lines from bottom up to value). Holger Vogt 2026-08-14 11:39:08 +0200
  • 2884721faf enable external set integer 'xbrushwidth' for arrowplot. Holger Vogt 2026-08-14 11:37:57 +0200
  • 784ce1f7eb Change exe name to ngspice_opus.exe in VS project. Holger Vogt 2026-08-14 00:46:18 +0200
  • e7fb53f6fc Add an arrowplot flag to plot, gnuplot commands for plotting signal strenth versus frequency with vertical arrows. An internal flag PLOT_ARROWS is set. With command 'plot' this is the same as the combplot flag. With 'gnuplot' this adds an extra drawing style using vectors. Holger Vogt 2026-08-14 00:45:29 +0200

  • ba36e3bdc9 Prevent VSRC PWL glitches: The fold is exact on paper, but floor() on a ratio of doubles can leave time a few ulp PAST the last point: measured at 7.5e-23 s after about 1900 periods of a 1 ns clock. The search below then matches no segment at all, drops out of the loop without assigning, and the source silently keeps value's initialiser of 0 V for that one timepoint. On a clock that is a dropout to zero in the middle of an edge -- a glitch a downstream flip-flop reads as two extra edges, which is far worse than the tiny timing error it comes from. Clamp so the last segment always matches. Alfredo Tomasini 2026-08-12 14:35:54 +0200

  • 64926499da pyplot: If on MSVC the top graph limit is slightly less (due to double precision deviations) than the vector contents, the graph will not be plotted in this area. Therefore extend the limits a bit (0.5%). Gnuplot: Use snprintf instead of sprintf. Reduce limits extension to 0.005. Holger Vogt 2026-08-09 14:15:15 +0200
