# Override configurations in ../example-sky130.yml

# Specify clock signals
vlsi.inputs.clocks: [
  {name: "clock_uncore", period: "30ns", uncertainty: "2ns"}
]

# Placement Constraints
# If overriding the placement constraints in example-sky130.yml,
# ensure one of the toplevel margin sides corresponding with the power pin metal layers
# is set to 0 so that Innovus actually creates those pins (otherwise LVS will fail).
# For example, in example-sky130.yml we set
#   par.generate_power_straps_options.by_tracks.pin_layers: 'met5'  # horizontal layer
# therefore we must also set:
#   vlsi.inputs.placement_constraints:
#     - path: "ChipTop"
#       ...
#       margins:
#         right: 0  # or left: 0
