For installation instructions, please see the relevant platform page.

Choose the package that corresponds to your development platform, i.e. the machine on which you will be running Tigress. Note that it is possible to cross-compile; for example, you can run Tigress on an Linux/x86/64 system and generate output that runs on Arm7.

Research use: Tigress is free to use for non-profit organizations.

Commercial use: If, after trying out Tigress, you decide to use it in a for-profit organization, you will need a license from the University of Arizona. Contact us and we will put you in touch with the university's licensing department
