FPGA Logic Analyzer: common questions
What microcontroller does the FPGA Logic Analyzer use?
The FPGA Logic Analyzer is built around the ICE40UP5K-SG48I, from the FPGA family.
How big is the FPGA Logic Analyzer PCB?
The FPGA Logic Analyzer measures 89.7 × 82.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the FPGA Logic Analyzer?
144 components, from 44 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the FPGA Logic Analyzer design files?
From the hack-a-tack/FPGA_Logic_Analyzer repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the FPGA Logic Analyzer design in my own project?
The repository has no license, so all rights stay with hack-a-tack. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FPGA Logic Analyzer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
