SETUP TIME Violations fixing Techniques

SETUP TIME Violations fixing Techniques

The following techniques are used to fix the Setup time violations
  1. Up-size the cell
  2. HVT to LVT conversion
  3. Add buffer on Data path
1).Up-size the buffer
  • get_cells
  • get_lib_cells -of_object cell_name  (which cell you want to up-size NOR2X0_HVT)
  • get_alternative_lib_cells cell_name
  • size_cell cell_name saed32hvt_ff1p16vn40c/NOR4X0_HVT (corresponding cell library with cell name )
2).HVT to LVT conversion
  • get_cells
  • get_lib_cells -of_objects U453 (cell name NOR4X0_LVT)
  • size_cell U453 NOR4X0_LVT  (U453 Instance name)
3).Add buffer
  • insert_buffer net_name BUFX4
Note: Here cell name means Instance name
