Gp4-hil: common questions

What microcontroller does the Gp4-hil use?

The Gp4-hil is built around the XC7A100T-1FTG256C, from the FPGA family.

How big is the Gp4-hil PCB?

The Gp4-hil measures 160 × 62 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gp4-hil?

450 components, from 70 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gp4-hil design files?

From the azonenberg/openfpga repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Gp4-hil design in my own project?

Yes, under the terms of its LGPL-3.0 license, which azonenberg chose for the repository.

Can I test firmware for the Gp4-hil 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.
