fusesoc VS de10-nano

Check out https://github.com/olofk/fusesoc. It gives you a command line build flow that can drive Vivado (along with many other eda tools via edalize https://github.com/olofk/edalize) without having to touch the GUI (though you might want it for programming the board, though FuseSoC can do that too).

Check out FuseSoC: https://github.com/olofk/fusesoc it can run Vivado builds for you (as well as many other tools). It may be less work to get FuseSoC setup then work out a CLI Vivado batch flow from scratch.

Also, the FuseSOC and LiteX projects both support the DE10 nano, and can be used to roll your own custom SOCs with RISC-V or OpenRISC cores.

Integration with the dependency and build tool I use (FuseSoc) is clumsy.

The "fusesoc" project may be of interest to you.

FuseSoC is an RTL package manager. It will automatically download the latest versions of required components when you build. It also comes with a bunch of great options for components here:

Have to correct this slightly: I just heard of my first HDL package manager in this thread. FuseSOC: https://github.com/olofk/fusesoc - Thanks u/gac_cag!

All signals are by default internal in qsys if you don't explicitly export them. So, if you want something out of the FPGA e.g. GPIO/LED you must export them. The column named export in qsys makes the signals appear in input/output ports of the module instance so that you can put them in top module i/o and assign pin locations using assignment editor. Partially explained here: https://github.com/zangman/de10-nano/blob/eef52965cba1386c441b738010e149589b8a0ed5/docs/Simple-Hardware-Adder_-Wiring-the-components.md

The Absolute Beginner's guide to DE10NANO (https://github.com/zangman/de10-nano/wiki for those who don't know) does have all the information you need for the fpga side.

what kind of help do you need? Given the wording, I guess you are talking about intel FPGAs. In that case, this is a nice guide even if you don't have that specific board: https://github.com/zangman/de10-nano/wiki

Anyways, feel free to just download and use the debian and archlinux images, perhaps you may still find them useful :).

Btw - just noticed you're using the de10-nano. In case you want to learn more about the SoC side of things, I have an absolute beginner's guide here - https://github.com/zangman/de10-nano/wiki. It walks you through the steps to building your own linux OS and writing your first HPS to FPGA project.

About a year ago, I published my wiki on the "Absolute beginner's guide to DE10-Nano". Here is the reddit post I made back then detailing all the topics covered (Build your own Debian OS, setting up dev environment etc).
