| * README: update windows build instructions for eigen, pythonSean Cross2019-04-021-2/+10
|/ | | | | | | | | | | | | The recent addition of "eigen3" to nextpnr necessitates the addition of "eigen" to the list of vcpkg packages to be installed on Windows. Add the 32- and 64-bit versions of eigen to the command issued to install various dependencies. Also document one possible build command, and note about unpacking python36.zip.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
