Designing FPGA or SoC circuits with power constraints #FPGA @HacksterIO
Via Adam Taylor om Hackster.io – we all like to think we’re good at making circuits but rarely do we put in the extra work to figure out how to best power a project, especially in restrictive power or thermal environments. Adam writes:
Several of the projects I am working on at the moment are required to work with power constrained supplies.
There are a number of reasons why the design is power constrained — from being expected to operate via a battery for a long period of time to operating in a environment where the thermal dissipation is tightly controlled.
Design tips listed include:
Create a power budget
Select the smallest device in the largest package available
Firm up on the IP blocks used, new IP to be created, pin out, clocking and reset strategy, etc.
Carefully consider the IO standard and configuration used
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
