mrg 7ba9e09e12 Incomplete precharge layer decoupling 2020-03-04 22:23:05 +00:00
Bastian Koppelmann 64bf93e4e5 bank: Connect instances by their individual bl/br names 
each module should be able to state how their bl/br lines are named. Here we
always connect port_data with the bitcell_array, so port_data needs function
that return the names of bl/br.
