| * | README: further specify required Boost packages for UbuntuSean Cross2018-11-221-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | UWhen installing Boost, you can either install libboost-all-dev, or install just the required packages. Previously, `libboost-dev` was the only required package listed. This adds `libboost-filesystem-dev libboost-thread-dev libboost-program-options-dev libboost-python-dev` to the list of required packages. It addresses issue #128.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During packing we replace them by standard SB_IO cells and create the 'fake' SB_GB that matches that IO site global buffer connection. It's done in a separate pass because we need to make sure the nextpnr iob have been dealt first so we have our final Bel location on the SB_IO. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

| * | ice40: Introduce the concept of forPadIn SB_GBSylvain Munaut2018-11-195-2/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Those are cells that are created mainly to handle the various sources a global network can be driven from other than a user net. When the flag is set, this means the global network usually driven by this BEL is in fact driven by something else and so that SB_GB BEL and matching global network can't be used. This is also what gets used to set the extra bits during bitstream generation. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

| | | | | | | | | | | | | | | | | | | | | | | | The icebox DB is a bit inconsistent in how global network connections are represented. Here we make it appear consistent by creating ports on the cells that can drive it. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

| * | | common/placer1: In random pick, only use grid if there is more than 64 BELsSylvain Munaut2018-11-192-8/+21
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | If you have a large grid and very few BELs of a given type, picking a random grid location yields very little odds of finding a BEL of that type. So for those, just put all of them at (0,0) and do a true random pick. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
