Какое средство моделирования схемы может использоваться с человечностью 16.04?

На основе опыта в использовании некоторых, здесь мои рекомендации на основе ссылки @P05TMAN предложенный и могут быть легко найдены на Хранилище программного обеспечения Ubuntu.

• Icarus Verilog
• Орел

Хотя они находятся больше на промежуточном/усовершенствованном уровне, они позволяют Вам делать более сложные операции и разрабатывать, но требует некоторого фона и знания программного обеспечения/языка.

Похож на Qucs, то, что рекомендуется в UbuntuEngineering wiki:

https://help.ubuntu.com/community/UbuntuEngineering

Это указано, чтобы быть доступным в Центре программного обеспечения Ubuntu

Используя apt search circuit, мы можем получить список доступных пакетов, который содержит слово "схема" где-нибудь в их описании. Я выбрал некоторых (11) кандидаты того списка, который казался наиболее относящимся ко мне и скопировал их описания с apt show PACKAGENAME здесь:

  GPL EDA -- Electronics design software (metapackage)

Description: GPL EDA -- Electronics design software (metapackage)
 The gEDA project has produced and continues working on a full GPL'd suite
 and toolkit of Electronic Design Automation tools. These tools are used
 for electrical circuit design, schematic capture, simulation, prototyping,
 and production. Currently, the gEDA project offers a mature suite of free
 software applications for electronics design, including schematic capture,
 attribute management, bill of materials (BOM) generation, netlisting into
 over 20 netlist formats, analog and digital simulation, and printed
 circuit board (PCB) layout.
 .
 This is a metapackage which depends on the components required for a
 typical gEDA installation.


gnucap/xenial 1:0.36~20091207-2 amd64
  GNU Circuit Analysis package

Description: 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. The output is produced as it
 simulates.  Spice compatible models for the MOSFET (level 1,2,3) and diode
 are included in this release.


gspiceui/xenial 1.1.00+dfsg-1build1 amd64
  Graphical user interface for gnucap and ngspice

Description: Graphical user interface for gnucap and ngspice
 Gspiceui is a graphichal user interface for the two freely available electronic 
 circuit engines: GNU-Cap and Ng-Spice. Current features are:
  * Import gschem schematic files using gentlist.
  * Load and parse circuit description (net list) files.
  * Provides a GUI interface for GNU-Cap OP, DC, AC and Transient analyses and
  generates appropriate simulator commands based on user input.
  * Provides a GUI interface for Ng-Spice DC, AC and Transient analyses and
  generates appropriate simulator commands based on user input.
  * The raw output may be viewed for any processes initiated by gspiceui.


kicad/xenial 4.0.2+dfsg1-4 amd64

Свободный ОРЕЛ
Я нашел его сегодня и испытал его. Это работает хорошее до сих пор. Это работает от рабочего стола в браузере как приложение. Я не попытался использовать его офлайн, чтобы видеть, работает ли это без интернет-соединения как другие подобные приложения, я имею на своем рабочем столе Ubuntu.
