Simulation and Analysis of Power and Thermal Management Policies

Simulation and Analysis of Power and Thermal Management Policies
by Daniel Payne on 11-18-2014 at 10:00 pm

Earlier this month I blogged about Power Management Policies for Android Devices, so this blog is part two in the series and delves into the details of using ESL-level tools for simulation and analysis. The motivation behind all of this is to optimize a power management system during the early design phase, instead of waiting until… Read More

Multiple clock domains in FPGAs have simplified some aspects of designs, allowing effective partitioning of logic. As FPGA architectures get more flexible in how clock domains, regions, or networks are available, the probability of signals crossing clock domains has gone way up.… Read More


Electro-Thermal Simulation of Power Transistors

Electro-Thermal Simulation of Power Transistors
by Daniel Payne on 09-25-2014 at 4:00 pm

Power transistors are commonly used in applications like: hybrid vehicles, electric vehicles, automotive, home appliances, LED lighting, TVs, power and energy. In the old days an engineering team could build their device with power transistors, then after production run some thermal testing to see if they guessed the proper… Read More


TCAD to SPICE

TCAD to SPICE

Power devices have historically been made from silicon (Si), which has reached the limit of electric power loss reduction. With the superior physical and electrical properties of silicon carbide (SiC), we can expect to see a significant expansion in the amount of electric power conversion of electrical equipment as well as reduced… Read More


MEMS+, Bringing MEMS into the Electronic World

MEMS+, Bringing MEMS into the Electronic World
by Paul McLellan on 09-19-2014 at 1:59 pm

One of the things about MEMS devices is that they almost always live on a chip that also contains the electronics necessary to process the output from the sensor. For example, an on-chip accelerometer for a car airbag deployment will contain the electronics necessary to process the signal from the sensor and end up with something… Read More


Know All About ESD and Save Your Chips & Systems

Know All About ESD and Save Your Chips & Systems
by Pawan Fangaria on 08-24-2014 at 7:30 pm

In this age of electronics, especially with so many different types of human held devices and more upcoming wearable devices, it’s utmost important to protect the massive circuitry inside those tiny parts in the devices from ESD related failures. The protection needs to happen at all stages – cells inside the chips, package… Read More


Electronic Thermal Management through Icepak

Electronic Thermal Management through Icepak
by Pawan Fangaria on 08-03-2014 at 8:30 pm

Last week my daughter was playing some games on my Google Nexus smartphone for a while when one of my friends called. When I picked up the phone, I couldn’t imagine it was so hot. There is no doubt; every electronic device today emits an order of magnitude higher heat than what it used to at most a decade ago. There is so much emphasis on … Read More


Open Source Verilog

Open Source Verilog
by Paul McLellan on 08-03-2014 at 8:01 am

Over the years there have been various open source EDA projects but none that has realized a full industrial strength design tool that has broad adoption and is strong enough to compete with similar products from the EDA industry.

Open source is clearly a great way to develop software. Lots of people can see all the source code and … Read More


Then, Python walked in for verification

Then, Python walked in for verification
by Don Dingee on 07-31-2014 at 12:00 am

Go ahead – type “open source” into the SemiWiki search box. Lots of recent articles on the IoT, not so many on EDA tools. Change takes a while. It has only been about five years since the Big Three plus Aldec sat down at the same table to work on UVM. Since then, Aldec has also gotten behind OS-VVM, and is now linked to a relatively new open… Read More
