 The steps above install the `YoWASP`_ FPGA toolchain, which is a good low-friction option, especially for people whose primary competence is not in software, since it does not require any additional installation steps. However, the YoWASP toolchain is noticeably slower compared to a native code code toolchain (usually by a factor of less than 2×). The YoWASP toolchain is also not available for all platforms and architectures; notably, 32-bit Raspberry Pi is not covered.
 
-If you already have the required tools (``yosys``, ``nextpnr-ice40``, ``icepack``) installed or are willing to `install <oss-cad-suite_>`__ them, you can update your profile to set the environment variable ``GLASGOW_TOOLCHAIN`` to ``system,builtin``, which prioritizes using the system tools over the YoWASP tools. The default value is ``builtin,system``, which causes the system tools to be used only if the YoWASP tools are not present or not runnable.
