| # Notes | |
| Since Architecture Definitons rely on yosys and VPR, it may be useful to override the default packaged binaries with | |
| locally supplied binaries. | |
| The build system allows this via environment variables matching the executable name. | |
| Here is a list of common environment variables to defined when doing local yosys and VPR development. | |
| * YOSYS : Path to yosys executable to use. | |
| * VPR : Path to VPR executable to use. | |
| * GENFASM : Path genfasm executable to use. | |
| There are more binaries that are packaged (e.g. VVP), but the packaged versions are typically good enough for most use | |
| cases. | |
| After setting or clearing one of these environment variables, CMake needs to be re-run. |
