Are you using simulink for code generation or something else? I used to work at a company that made automotive controllers and a simulink "platform" for developing controls on them, and I occasionally flirt with starting a similar company that uses a cheaper/open source toolchain, but always come up empty handed. There are some academic libraries and papers around the Xcos ecosystem, but nothing near production level that I could find.
