|/ | | | | | | | | This is mostly for the benefit of PLL placement because the D_IN_x ports are used for other purposes when PLL is enabled so we need to make sure nothing is connected there already. (even an unused net is too much) Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

|/ | | | | Using a copy constructor to set the logfile is the only thing that stops compilation with the libstdc++ shipping with gcc 4.8 (maybe 4.7)

|/ | | | | | | | | | | | | 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.

| * HeAP: Make HeAP placer optionalDavid Shah2019-03-226-15/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
