Mentor Graphics is a US-based electronic design automation (EDA) multinational corporation for electrical engineering and electronics, headquartered in Wilsonville, Oregon. Founded in 1981, the company was acquired by Siemens in 2017. Since 2021, the former Mentor Graphics operates as a division at Siemens named Siemens EDA.
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).
Accellera Systems Initiative (Accellera) is a standards organization that supports a mix of user and vendor standards and open interfaces development in the area of electronic design automation (EDA) and integrated circuit (IC) design and manufacturing. It is less constrained than the Institute of Electrical and Electronics Engineers (IEEE) and is therefore the starting place for many standards. Once mature and adopted by the broader community, the standards are usually transferred to the IEEE.
Silvaco Inc. develops and markets electronic design automation (EDA) and technology CAD (TCAD) software and semiconductor design IP (SIP).

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 Amps at sub-1V VDD levels with AC and DC margins in the tens of millivolts. Very little DC voltage drop can thus be tolerated on the power distribution network.
Switching Control Techniques address electromagnetic interference (EMI) mitigation on power electronics (PE). The design of power electronics involves overcoming three key challenges:
- power losses
- EMI
- harmonics
