In netlist the connection is, IO1 <-> IO2_a <-> IO3_a IO2_a <-> IO3_b Note: IO2_a branched out to IO3_a and IO3_b. But in the SDF, INTERCONNECT IO3_a IO3_b (....) INTERCONNECT IO3_b IO3_a (....) Note: IO3_a and IO3_b are driving each other according to the SDF file. If IO1 is a toggling clock, while IO3_a is Hi-Z, can this cause IO3_b to become Hi-Z because of the SDF interconnect?
