| * | ice40: Take placed SB_GBs into account when placing PLLsSylvain Munaut2019-04-161-9/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the PLLs drive global networks, we need to account for already existing and placed SB_GBs when trying to place/pack them. Theses can be user instanciated SB_GBs with BEL attribute, or SB_GB_IOs that got converted during the IO packing. This patch assumes that: - If a PLL is used the output A global network is always used, even if there is no connection to the global output pin - If a PLL with a singe output is used, then the B output global network is still free to be used by whatever.

|/ / | | | | | | | | | | | | | | | | 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>

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