No possible routing path from cluster-external source (LB_SOURCE) to cluster-internal sink (LB_SINK accessible via architecture pins: SB_DFFN[0].C[0]): needed for net 'clk' from net pin 'clk.inpad' to net pin '$auto$simplemap.cc:420:simplemap_dff$83.C'
Net 'clk' is impossible to route within proposed BLK_TL-PLB cluster
Failed route at end, repack cluster trying detailed routing at each stage.
