This page is a comparison ofelectronic design automation (EDA) software which is used today to design the near totality of electronic devices. Modern electronic devices are too complex to be designed without the help of a computer. Electronic devices may consist ofintegrated circuits (ICs),printed circuit boards (PCBs),field-programmable gate arrays (FPGAs) or a combination of them. Integrated circuits may consist of a combination of digital and analog circuits. These circuits can contain a combination of transistors, resistors, capacitors or specialized components such as analog neural networks, antennas or fuses.

The design of each of these electronic devices generally proceeds from a high- to a low-level of abstraction. For FPGAs the low-level description consists of a binary file to be flashed into the gate array, while for an integrated circuit the low-level description consists of a layout file which describes the masks to be used for lithography inside a foundry.

Each design step requires specialized tools, and many of these tools can be used for designing multiple types of electronic circuits. For example, a program for high-level digital synthesis can usually be used both for IC digital design as well as for programming an FPGA. Similarly, a tool for schematic-capture and analog simulation can generally be used both for IC analog design and for PCB design.

In the case ofintegrated circuits (ICs) for example, a single chip may contain today more than 20 billiontransistors and, as a general rule, every single transistor in a chip must work as intended. Since a singleVLSImask set can cost up to 10-100 millions,trial and error approaches are not economically viable. To minimize the risk of any design mistakes, the design flow is heavily automatized. EDA software assists the designer in every step of the design process and every design step is accompanied by heavy test phases. Errors may be present in the high-level code already, such as for thePentium FDIV floating-point unit bug, or it can be inserted all the way down to physical synthesis, such as a missing wire, or atiming violation.

The world ofelectronic design automation (EDA) software forintegrated circuit (IC) design is dominated by the three vendorsSynopsys,Cadence Design Systems andSiemens EDA (Formerly Mentor Graphics, acquired in 2017 bySiemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.

These vendors offer software bundles which allow to cover the full spectrum of IC design, from HDL synthesis to physical synthesis and verification.

The development of EDA software is tightly connected with the development oftechnology nodes. The properties of a specific semiconductor foundry, such as the transistor models, the physical characteristics and the design rules, are usually encoded in file formats which are proprietary to one or more EDA vendors. This set of files constitutes theprocess design kit (PDK) and it is usually developed as a joint effort between the foundry and an EDA vendor. Foundries therefore usually release PDKs which are compatible only for one specific EDA bundle. The information contained inside PDKs is usually considered confidential. PDKs are therefore usually protected bynon disclosure agreements (NDAs) and may be shipped in an incomplete or in an encrypted form to the designers.

Of these, LTSpice and Micro-cap are free proprietary applications based onSPICE. Micro-Cap was released as freeware in July 2019, when its parent company Spectrum Software closed down while LTSpice has been free for a long time.

Free and open-source (FOSS) EDA software bundles are currently under fast development mainly thanks to theDARPA andGoogle's openROAD project. The OpenROAD project offers a complete stack of tools from high-level synthesis down to layout generation^[7] The flow includesYosys for logic synthesis,OpenLane for physical synthesis and targets the SkyWater 130 nm PDK. The flow is currently utilized to submit design for free fabrication atGoogle.^{[8][9][better source needed]}

High-level synthesis software can generally be used for the design of bothapplication-specific integrated circuits (ASICs) andfield-programmable gate arrays (FPGAs). Most high-level synthesis software is used to edit and verify code written in one of the mainstreamhardware description languages (HDL) likeVHDL orVerilog. Other tools instead operate at a higher level of abstraction and allow to synthesize HDL code starting from languages likeChisel orSpinalHDL. The higher abstraction of such languages enablesformal verification of HDL code.^{[10][11][better source needed]}

This list does not include schematic editors or simulators since these can generally be used both for Integrated Circuits (ICs) and for Printed Circuit Board (PCB) as long as device models are available.
