As it said in title, how to find out a instance which drives another inst's port? Use dbGet??
Waiting your answer.
what is special inst's port???
Just find out the inst which drive a cell's port.
e.g. find the friver of top_fifo_reg1_2_/D.
top_fifo_reg1_2_ is an inst, D is top_fifo_reg1_2_'s input port.
