Still there exist certain hold mode violations after using the command optDesign -postRoute -hold.. What to do?there is no such thing as free lunch. hold fixes usually incur penalties... very often delay cells are added to slow down hold-critical paths.
you can go back one stage and perform your post route opt with a higher hold margin.
you can also run a dedicated Hold Opt round. in Innovus, this is achieved with optDesign -postRoute -hold
