There's two possibilities.

- Rocket has no automated build flow that checks whether committed code is synthesizable.

- you aren't using the same flow as them. I struggled to find what synthesis tools they used just now so I don't blame you!

The code that is committed isn't directly synthesizable, it needs to be transformed to HDL by a tool that is itself being updated.

I tried what looked to be a supported flow, generate Verilog for FPGAs then synthesize it for Xilinx Zynq devices. The Verilog errors looked correct to me.

I saw a little info on that at https://github.com/ucb-bar/fpga-zynq

I guess you are referring to that?

It's supposed to be a relatively mature tool so there's got to be a version that works ok.
