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.	2017-10-20 15:18:39 +01:00
