Determine the absolute timing of a schedule based on the timing constraints.

This function determines absolute timings for every operation in the schedulables. It does this by:

  1. iterating over all and elements in the schedulables.

  2. determining the absolute time of the reference operation - reference point "ref_pt" of the reference operation defaults to "end" in case it is not set (i.e., is None).

  3. determining the start of the operation based on the rel_time and duration of operations - reference point "ref_pt_new" of the added operation defaults to "start" in case it is not set.

Parameters:

  • schedule – The schedule for which to determine timings.

  • config – Compilation config for QuantifyCompiler.

  • time_unit – Whether to use physical units to determine the absolute time or ideal time. When time_unit == "physical" the duration attribute is used. When time_unit == "ideal" the duration attribute is ignored and treated as if it is 1. When time_unit == None it will revert to "physical".

Returns:

: The modified schedule where the absolute time for each operation has been determined.

Raises:

NotImplementedError – If the scheduling strategy is not SchedulingStrategy.ASAP

Returns:

: True if valid

Can be used as a debugging tool to spot any circular references.
