Debian Electronics Simulation packages

GHDL is a compiler and simulator for VHDL, a Hardware Description Language. GHDL is not an interpreter: it allows you to analyse and elaborate sources to generate machine code from your design. Native program execution is the only way for high speed simulation.

GHDL offers three machine code generation backends: one based on GCC, one using the LLVM compiler suite and a GHDL specific one called mcode. These are available in the ghdl-gcc, ghdl-llvm and ghdl-mcode packages respectively. Both the GCC and LLVM backends create highly optimized code for excellent simulation performance while simulations compiled with the GCC backend also allow coverage testing using gcov. The mcode backend creates less performant code but makes up for it with much faster compilation. It is therefore preferable for smaller projects without large or long running simulations.

Multiple backends can be installed at the same time and selected by either invoking the desired GHDL directly (as ghdl-gcc, ghdl-llvm or ghdl-mcode) or by providing a GHDL_BACKEND environment variable (containing gcc, llvm or mcode) while invoking ghdl.

This package is a dependency package that will make sure at least one backend is installed.

Gnucap jest uniwersalnym symulatorem obwodów elektrycznych. Służy do wykonywania nieliniowych analiz prądu stałego i stanów przejściowych, analiz Fouriera oraz analiz prądu zmiennego, linearyzowanych w punkcie pracy. Jest w pełni interaktywny oraz sterowany z wiersza poleceń. Można go również uruchamiać w trybie wsadowym lub w roli serwera.

Ten pakiet zawiera główny plik wykonywalny oraz gnucap-modelgen.

GTKWave jest przeglądarką do plików VCD (Value Change Dump), które są zwykle tworzone przez cyfrowe symulatory obwodu elektrycznego. (Pliki te nie mają związku z płytami wideo CD!).

Gwave jest narzędziem do przeglądania danych analogowych, takich jak dane wyjściowe symulacji Spice.

Gwave może odczytywać pliki "surowe" ze spice2G6, spice3F5 lub ngspice oraz tabelarycznego formatu ASCII, nadającego się do użycia z GnuCAP lub z narzędziami własnej konstrukcji. Może również odczytywać wiele plików binarnych i ASCII, zapisywanych przez komercyjne symulatory typu spice takie jak: HSPICE, tspice oraz nanosim.

Obsługuje wiele "paneli" (siatek) służących do wyświetlania wielu zmiennych. Udostępnia dwa kursory w kształcie pionowych pasków do pomiarów różnic czasowych. Umożliwia załadowywanie wielu plików w celu porównywania wyników kilku symulacji.

IRSIM is a tool for simulating digital circuits. It is a "switch-level" simulator; that is, it treats transistors as ideal switches. Extracted capacitance and lumped resistance values are used to make the switch a little bit more realistic than the ideal, using the RC time constants to predict the relative timing of events.

Icarus Verilog w zamierzeniu ma kompilować wszystko z Verilog HDL zgodnie ze standardem IEEE-1364. Cel nie został jeszcze osiągnięty. Obecnie radzi sobie z obsługą różnych działań strukturalnych i zachowań układów.

Kompilator potrafi przeprowadzić symulację i zapisać schemat układu w formacie EDIF.

NGSpice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. It supports compiled Verilog-A models through the built-in OSDI interface.

NGSpice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools.

Oregano is a GNOME application for schematic capture and printing of electronic circuits. It can simulate the circuits using Gnucap, ng-spice or Berkeley spice.

Simulide is a real time electronic circuit simulator intended for hobbist and student experimentation with simple general purpose electronic circuits and PIC, AVR and Arduino microcontroller simulations.

TkGate is a digital circuit editor and simulator with a Tcl/Tk based interface. TkGate includes a large number of built-in devices including basic gates, memories, ttys and modules for hierarchical design. The simulator can be controlled either interactively or through a simulation script. Memory contents can be loaded from files, and a microcode/macrocode compiler (gmac) is included to create tkgate memory files from a high-level description. The simulator supports continuous simulation, single step simulation (by clock or epoch) and breakpoints. Save files are in a Verilog-like format.

TkGate also includes a number of tutorial and example circuits which can be loaded through the "Help" menu. The examples range from a simple gate-level 3-bit adder to a 16-bit CPU programmed to play the "Animals" game.

TkGate has a multi-language interface with support for English, Japanese, French and Spanish.

Verilator is the fastest free Verilog HDL simulator, and beats many commercial simulators. It compiles synthesizable Verilog (not test-bench code!), plus some PSL, SystemVerilog and Synthesis assertions into C++ or SystemC code. It is designed for large projects where fast simulation performance is of primary concern, and is especially well suited to generate executable models of CPUs for embedded software design teams.

This is a free VHDL simulator with these features:

• Has a graphical waveform viewer.
• Has a source level debugger.
• Is VHDL-93 compliant.

Cver is a full 1995 IEEE P1364 standard Verilog simulator. It also implements some of the 2001 P1364 standard features. All three PLI interfaces (tf_, acc_, and vpi_) are implemented as defined in the IEEE 2001 P1364 LRM.

This package contains Python bindings for the GNU Circuit Analysis Package.

Gnucap is a general purpose circuit simulator. It performs nonlinear dc and transient analyses, Fourier analysis, and ac analysis linearized at an operating point. It is fully interactive and command driven. It can also be run in batch mode or as a server.

Easyspice is a graphical frontend for the electrical circuit simulator Spice. It is by default connected to the geda package and ngspice but can be used as a frontend for other spice simulators programs as well.
