------------------------------------------------------------------- Mon Jan 1 07:58:35 UTC 2024 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 42: * KLU matrix solver has been added to the venerable Sparse 1.3 * Verilog-A device models (copiled by OpenVAF) now support small signal noise simulation. * Digital C coded circuit blocks may be read by the code model d_process. * Verilog (digital) circuits, compiled with Verilator, may be read into ngspice by new code model d_cosim. * For additional new features see the included NEWS file. - Update to version 41: * Analog node changes in VCD file output. * Read Touchstone file for S parameter simulation. * Completely renewed XSPICE d_osc code model. * Updates to commands setscale, compose, eprvcd, iplot, and listing. * Option FREQ for E and G sources. * New dot command .libsave. ------------------------------------------------------------------- Wed Apr 5 12:40:01 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 40: * New features: + VBIC: Add optional parameters for determining the operation region + VBIC: Add bvbe, bvbc, bvce, bvsub as SOA parameters + Add inertial delay to all basic digital code models, make it available for U devices + VDMOS default parameters are now similar to IRF540 IRF9540 + Add function atanh to .control section + Add a scale factor 'a' (atto, 1e-18) * Bug fixes: + ngspice-40 is mostly a bug-fix release. In conjunction with KiCad and shared ngspice, inappropriate user inputs have led to crashing ngspice. + bugs no. 331, 619, 620, 624 have been fixed + 9 crash bugs (double delete, access NULL pointer etc) removed which have occurred mostly due to incomplete or faulty inputs. + Memory leaks removed - Moved user manual (ngspice-doc) to separate source package. ------------------------------------------------------------------- Tue Feb 14 19:18:01 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 39: * New features: + ngspice now offers simulation with Verilog-A models, using its new OSDI interface and the OpenVAF model compiler. This enhancement enables access to all modern compact models for short channel MOS, FinFets, double gate transistors, SiGe bipolars, and III-V HEMTs. + ngspice now supports nearly all features of digital PSPICE compatible U devices (instances).
