David Shah ca35e566d4 Modify icebox.py so it generates a 5k chipdb 2017-10-20 19:13:23 +01:00

David Shah 172d561b01 Fix make_ram40 for UltraPlus 
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.

David Shah 42047c6114 Fix case where make_prim allocates all global buffer pins 
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.
