A small example for the bidirectional buffers that connect long lines. The configuration
bit (00_45 for LVB_L12<-->LVB_L12) confiures the direction of the buffer.

Probably only works for with the Artix 7 settings because contains
hardcoded slice addresses.

Expected output is something like this:


	$ python3 ../../utils/segprint.py design_a.bits INT_L_X12Y132 INT_L_X14Y132 INT_L_X16Y132

	seg SEG_CLBLL_L_X12Y132
	bit 00_45

	seg SEG_CLBLL_L_X14Y132

	seg SEG_CLBLL_L_X16Y132
	bit 00_45


	$ python3 ../../utils/segprint.py design_b.bits INT_L_X12Y132 INT_L_X14Y132 INT_L_X16Y132

	seg SEG_CLBLL_L_X12Y132

	seg SEG_CLBLL_L_X14Y132
	bit 00_45

	seg SEG_CLBLL_L_X16Y132
