If you just want the latest bit files then the easiest option is to grab

them from the outputs of the CI tools which are linked from

https://github.com/orbcode/orbtrace/actions

To build on Linux you will need yosys (https://github.com/YosysHQ/yosys),

nextpnr (https://github.com/YosysHQ/nextpnr) and, optionally,

a GCC RISC-V toolchain (https://github.com/riscv-collab/riscv-gnu-toolchain).

You can also get everything as part of oss-cad-suite

(https://github.com/YosysHQ/oss-cad-suite-build), or look at the CI

workflow at https://github.com/orbcode/orbtrace/blob/main/.github/workflows/build.yml

Dependancies such as Linux, Amaranth and Migen are automatically downloaded

as part of the build process, so you don't need to get those manuallly...and

indeed, your versions won't be used even if you do.

ORBTrace has been sucessfully built on OSX and Linux (Specifically Ubuntu). If

you have any problems building on your platform please drop us a note and

we can expand the instructions.
