Subject: Specify top-level module in Lattice Diemond build script.
X-Git-Tag: 24jan2021_ls180~1742^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef511e7edcddf7b13c56a5e41c08042801bee9ff;p=litex.git

Specify top-level module in Lattice Diemond build script.

When building multi-source files the toolchain gets confused as to which
module is top-level. This ensures that the build_name of the design is
selected.
