Module libreda_sta::models::ndlm_cell_delay

Implementation of the CellDelayModel using the non-linear delay model (NDLM) with data from a liberty library.

Structs

• NDLMCellModel
  Parameters
• NDLMConstraint
  Constraint between a related pin and a constrained pin.
• NDLMDelay
  Difference of two arrival times.
• NDLMOutputLoad
  Load capacitance.
• NDLMRequiredSignal
  Slew rate and edge polarity of a signal.
• NDLMSignal
  Slew rate and edge polarity of a signal.
• NDLMSlack
  Slew rate and edge polarity of a signal.

Enums

• DelayModelType
  Specify what delay model to use. This implementation of the NDLM delay model can also fall back to a constant delay model.
• EdgePolarity
  Edge polarity of a changing signal.
• MinMax
  Index type for selecting minimal or maximal values.
• RiseFall
  Index type for selecting edge types.

Functions

• convert_edge_polarity 🔒
  Resolve the edge polarities which need to be respected. An unknown polarity is translated to two polarities “rise” and “fall”.
