21.14.38.1 Arguments

delay_value

Specifies a floating point number in nanoseconds that represents the required maximum delay value for specified paths.

-from from_list

• If the path starting point is on a sequential device, the tool includes clock skew in the computed delay.
• If the path starting point has an input delay specified, the tool adds that delay value to the path delay.
• If the path ending point is on a sequential device, the tool includes clock skew and library setup time in the computed delay.

• If the ending point has an output delay specified, the tool adds that delay to the path delay.

  Specifies a list of timing path starting points. A valid timing starting point is a clock, a primary input, an inout port, or a clock pin of a sequential cell.

-to to_list

Specifies a list of timing path ending points. A valid timing ending point is a clock, a primary output, an inout port, or a data pin of a sequential cell.

-through through_list

Specifies a list of pins, ports, cells, or nets through which the timing paths must pass.
