Today, more and more electronics from air bag sensors to safety and convenience features are being added to cars, revolutionizing automotive safety and electronics.

With new electronic technologies, there’s always a risk something will fail. Simulation of electronic circuits to verify their functionality and reliability based on component tolerances, temperature variations, and other parameters becomes critical. It is crucial for automotive companies to perform yield and reliability analysis through exhaustive simulations to ensure there are no recalls due to field failures.


Meeting Rigorous Automotive Requirements

Electrical systems are controlling more of a vehicle's reliability, performance, and environmental features—from airbags to all-wheel drive, GPS to advanced driver assistance systems (ADAS), and cameras to infotainment systems. Vehicles today are trending to more than 100 ECUs distributed under the hood and in the interior—creating a range of challenges in communication, coordination, power distribution, and other areas.


Common challenges include:

Connectivity Issues

Wiring connectivity issues that force the adoption of “drive-by-wire”


Distribution and hybrid drives

Power distribution and the introduction of hybrid drives, which are propelling miniaturization of very high-power densities in power electronics


Systems Modeling

Automotive embedded systems can be modeled at multiple levels of abstractions, including functional requirements, hardware architecture, and software requirements leading to final implementation


Mixed-signal simulation

The number of sensors in automobiles have been increasing at an exponential level from tire pressure sensors to oxygen level sensors, etc. All of these sensors are mixed-signal sensors with digital control loops requiring the capability of mixed-signal simulations


Virtual prototyping

Faster time to market by verifying the hardware and software integration is tested way in advance before building the hardware


Early software validation

Validating how the complete system will function per specification in software can significantly reduce cost of actually building the hardware and then addressing any field failures and/ or recalls

"Whether you’re prototyping simple circuits, designing complex systems, or validating component yield and reliability, OrCAD PSpice technology provides the best, high-performance circuit simulation to analyze and refine your circuits, components, and parameters before committing to layout and fabrication"



Applications of power electronics extend across almost every industry ranging from consumer, to high-end space and defense application segment, all having their end products bound by the same goal of reliability, efficiency, simplicity, performance, control and unique set of challenges to accurately characterize and simulate.


PSpice® technology offers mixed-signal simulation and system-level analysis capabilities across different levels of abstraction across low- to high-power applications, including electric vehicles to data centers, to wearables, renewables, and the power grid. Known for its accuracy and high performance in power supply simulation technology as well as the ability to integrate with OrCAD® capture and Allegro® solution, PSpice simulation program makes power supply analysis simple.


Looking beyond the Power Supply Design Limitations

Worried about environmental regulations, heat dissipation, power supply stability, or cost and form factor? Whether you’re designing switch model power supply (SMPS), power amplifiers, invertors, or traditional linear voltage regulator circuits, you need to overcome the common challenges of:

High power

Difficult to characterize accurately in the lab, requires models for high voltage high power IGBT Module such as power semiconductors


“Multi-Rate” simulation problems

Requires 1000’s of input-signal cycles to achieve synchronization


Magnetic Component Requirements

Requires special models for magnetic components involving “nonlinear magnetics,” etc.


Low-Power Design

What is Internet of Thing (IoT) ?

While everyone has a different outlook on Internet of Things, there is a common agreement to the NEED of sophisticated mixed signal verification tools with ties to systems-level tools for full functionality testing. With the downsizing of connection and technology costs,there is a significant increase in devices with built-in WiFi and sensors with smartphone usage.

Devices like sensors, actuators and recently invented monitoring and control devices—which help in analyze and optimize our world—are creating a perfect storm for IoTs used in power supply and automotive markets. PSpice® technology, with its large simulation library and high performance (switching at high speed) provides the ultimate solution for the IoT market.

Addressing the demanding needs of IoT and Innovation

Business Insider Intelligence estimates that nearly $6 trillion to be spent on IoT solutions over the next five years, with other research firms estimating 50-100 billion devices to be connected to the internet in the same timeframe. This sets high expectations in this increasingly competitive market for new package and board technologies to satisfy the growing hunger for innovation leading to successful IoT products. How do you handle the common needs for the electronic components such as the ones with the smallest form factor like wearables and ultra-low power to larger SoC designs?




In IoT devices, power is very critical since the devices need to run for days/weeks/months/years. Simulations can help you minimize power consumption in these devices


Mixed-signal challenges

Analog and digital integration, interface and communication standards, and the combination of sensor systems has increased the complexity since it includes analog mixed signal, RF-wireless and digital microcontrollers among chip, package and board


Design form factor limitations

IoT products are driven by the need for the smallest form factor (think wearables) and ultra-low power (for longer battery life) that require advanced simulation and analysis


Model availability

Customers need models supporting multiple different abstraction levels so that they can trade off performance vs. accuracy. PSpice technology supports abstraction levels ranging from circuit level, to behavioral to C/C++/SystemsC
