Merge pull request #260 from xobs/windows-eigen-docs 
README: update windows build instructions for eigen, python
 2019-04-02 12:41:25 +01:00
Sean Cross 638f84a622 README: update windows build instructions for eigen, python 
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.

David Shah 7142db28a8 HeAP: Make HeAP placer optional 
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.
