A new generation of integrated logic analyzers for today’s FPGAs
SUMP3 is a new generation of the SUMP2 ILA (Integrated Logic Analyzer) that was first introduced in 2016 by Black Mesa Labs.
Like SUMP2, SUMP3 uses real-time hardware RLE (Run Length Encoding) compression to potentially store millions of clocked time samples in just a few thousand RAM cells (mileage may vary).
SUMP3 is designed with 2nm FPGAs with abundant RAM in mind. Even today’s 16nm AMD/Xilinx VU9P with 3 chiplets has over 2000 1Kx36 BRAMs, 1000 8Kx36 UltraRAMs and 2 million D flip-flops.
The Verilog RTL and Python GUI software for SUMP3 is available on GitHub here.

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.
