* Fix make_ram40 for UltraPlusDavid Shah2017-10-201-3/+7
| | | | | | Sometimes make_ram40 was assigning too many IO pins, causing a placment failure, and also sometimes connecting a global clock net to WCLKE or RCLKE which was also causing a placment failure.
* Fix case where make_prim allocates all global buffer pinsDavid Shah2017-10-201-1/+21
| | | | | | | | This is a low probability bug more likely to show up in low pin count devices with few GBINs. In rare cases make_prim would constrain all of the global buffer capable pins but not the clock input. icecube would then fail to place the clock input. This is fixed by always constraining the clock if all GBIN pins are used.
