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. test: test case for diode DC working with SH test: add transient analysis to osdi_diode test test: added docu text to osdi_diode test test: added test case directories fix: bug in osdi_load test: small change to netlist fix: implement DEVunsetup fix: correct behaviour for MODEINITSMSIG test: osdi diode enable all analysis modes removed netlist ignoring test results added the build of the diode shared object to the python test script deleting old stuff and always rebuilding the shared object added diode_va.c to the repo preparing CI Create .gitlab-ci.yml file (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. test: update tests to new command fix: do not ignore first parameter feat: implement log message callback fix: don't generate ddt matrix/rhs in DC sweep fix: missing linker script update to osdi 0.3 (testing) simplify test cases, fix bug (testing) multiple devices test improvement (testig) node collapsing bugfix test: increase tolerance in tests feat: update to newest OSDI header fix: temperature update dt behaviour fix: ignored models fix: compilation script fix: allow hicum/l2 to compile with older c++ compilers fix: set required compiler flags for osdi fix: disable x by default fix: add missing SPICE functions fix: update diode to latest ngspice version feat: implement python CMC test runner doc: Add README_OSDI.md fix: make testing script work with python version before 3.9 fix: free of undefined local variable fix: do not calculate time derivative during tran op update osdi version fixes for compilation on windows |

README
README for NGSPICE ================== Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Spice3 does not need any introduction, is the most popular circuit simulator. In over 30 years of its life Spice3 has become a de-facto standard for simulating circuits. Cider couples Spice3f5 circuit level simulator to a device simulator to provide greater simulation accuracy of critical devices. So you may create device models for diodes, bipolar, JFet and MOSFETs derived from their cross-sectional structures and materials. Xspice is an extension to Spice3C1 that provides code modelling support and simulation of digital components through an embedded event driven algorithm. Ngspice is, anyway, much more than the simple sum of the packages above, as many people contributed to the project with their experience, their bug fixes and their improvements. If you are interested, browse the site and discover what ngspice offers and what needs. If you think you can help, join the development team. Ngspice is an ongoing project, growing everyday from users contributions, suggestions and reports. What we will be able to do depends mostly on user interests, contributions and feedback. USER DISCUSSION FORUMS: ----------------------- For discussions on ngspice, there are five discussion forums, to be found at https://sourceforge.net/p/ngspice/discussion/. These typically provide quick answers to any question concerning ngspice. A new section on 'tips and examples' assembles useful tips provided by maintainers and users. MAILING LISTS: ------------- There are two mailing lists dedicated to the use and development of ngspice. * ngspice-users@lists.sourceforge.net: This list is the list for the users of the ngspice simulator. * ngspice-devel@lists.sourceforge.net: ngspice development issues. Developers and "want to be" developers should subscribe here. To subscribe the list(s), send a message to: <ngspice-users-subscribe@lists.sourceforge.net> <ngspice-devel-subscribe@lists.sourceforge.net> WEB SITEs: -------- This project is hosted on Sourceforge.net. The home page is https://ngspice.sourceforge.io The page offering source code, MS Windows executables, and user interaction is https://sourceforge.net/projects/ngspice
