Mentor Graphics Corporation was a US-based electronic design automation (EDA) multinational corporation for electrical engineering and electronics, headquartered in Wilsonville, Oregon. Founded in 1981, the company distributed products that assist in electronic design automation, simulation tools for analog mixed-signal design, VPN solutions, and fluid dynamics and heat transfer tools. The company leveraged Apollo Computer workstations to differentiate itself within the computer-aided engineering (CAE) market with its software and hardware.
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs).
Synopsys, Inc. is an American electronic design automation (EDA) company headquartered in Sunnyvale, California, that focuses on silicon design and verification, silicon intellectual property and software security and quality. Synopsys supplies tools and services to the semiconductor design and manufacturing industry.

This page is a comparison of electronic 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 of integrated 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.

Power integrity or PI is an analysis to check whether the desired voltage and current are met from source to destination. Today, power integrity plays a major role in the success and failure of new electronic products. There are several coupled aspects of PI: on the chip, in the chip package, on the circuit board, and in the system. Four main issues must be resolved to ensure power integrity at the printed circuit board level:
- Keep the voltage ripple at the chips pads lower than the specification
- Control ground bounce
- Control electromagnetic interference and maintain electromagnetic compatibility: the power distribution network is generally the largest set of conductors on the circuit board and therefore the largest (unwanted) antenna for emission and reception of noise.
- Maintaining a proper DC voltage level at the load at high currents. A modern processor or field-programmable gate array can pull 1–100 A from a sub-1 V power rail with voltage margins in the tens of millivolts. Very little DC voltage drop can thus be tolerated on the power distribution network.
