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
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
