* HeAP: Make HeAP placer optionalDavid Shah2019-03-221-1/+18
| | | | | | | | | | | | | A CMake option 'BUILD_HEAP' (default on) configures building of the HeAP placer and the associated Eigen3 dependency. Default for the iCE40 is SA placer, with --heap-placer to use HeAP Default for the ECP5 is HeAP placer, as SA placer can take 1hr+ for large ECP5 designs and HeAP tends to give better QoR. --sa-placer can be used to use SA instead, and auto-fallback to SA if HeAP not built.
