hackerfooVPR is packing both the input and output pads in the same IOPAD. How do I prevent this? I could use modes for now, but this will prevent input and output on the same pin.19:32
hackerfooI think I need a third mode with an IOBUF.19:34

sf-slack3<mkurc> @hackerfoo: Is that an error? Because from my understanding that is how actually an input/output pin should work in VPR.20:43
hackerfoomkurc: If I make a simple `assign out = in` design, both pins would get packed together before they get a chance to be placed based on the PCF/io.place.20:46
hackerfooThen it's too late, because there is only one cluster.20:47
sf-slack3<mkurc> oh20:47
hackerfooSo it's an artifact of thel separation of phases.20:49
hackerfoo*the20:49
sf-slack3<mkurc> So maybe try inserting a LUT there. Try `assign out = !in` That should translate into a LUT and in turn force VPR to separate nets for those pins20:53
hackerfooVPR routes now with modes for IBUF/OBUF if I manually edit top_io.place, so now I need to change prjxray_create_ioplace.py to lookup the block names in top.net.21:13
