SDF Backannotation

The SDF file could specify different delays between output port lout1
and input port rightin and output port botout and input port
rightin. The ports do not have to be on the same hierarchical level.
An example for the entries that specify these different delays is as
follows:
(CELL
(CELLTYPE "stim")
(INSTANCE stim)
(DELAY
(ABSOLUTE
(INTERCONNECT stim.left1.bot1.botout stim.right1.rightin (2))
(INTERCONNECT stim.left1.lout1 stim.right1.rightin(1))
)
)
)
These entries specify a 2 time unit delay between the output port
botout and the input port rightin, and a 1 time unit delay between
output port lout1 and input port rightin.
