Automated multi-stage design flow based on final quality of result

A system comprising:

• a memory storing instructions;
• and
• a processing device, coupled with the memory and to execute the instructions, the instructions when executed cause the processing device to:
• receive instructions relating to design iterations for a design flow to design a circuit, wherein the design flow comprises a sequence of at least two stages, and each stage produces an output design of the circuit from an input design of the circuit in accordance with parameters for that stage;
• execute a plurality of design iterations in accordance with the instructions;
• wherein each design iteration selects parameter values for a subflow of one or more stages, and the design iterations include final QoR-based design iterations that select parameter values for a non-final stage of the design flow based on a final QoR of the design flow, and the instructions specify parameter values that are given priority during the design iterations;
• and
• adapting the final QoR-based design iterations based on the final QoRs produced in previously executed design iterations by sequences that include all stages in the design flow.

A non-transitory computer readable medium comprising stored instructions, which when executed by a processing device, cause the processing device to:

• execute a plurality of design iterations for a design flow to design a circuit, wherein the design flow comprises a sequence of at least two stages, each stage produces an output design of the circuit from an input design of the circuit in accordance with parameters for that stage, each design iteration selects parameter values for a subflow of one or more stages, and the design iterations include final QoR-based design iterations that select parameter values for a non-final stage of the design flow based on a final QoR of the design flow;
• and
• adapting the final QoR-based design iterations based on the final QoRs produced in previously executed design iterations by sequences that include all stages in the design flow;
• and
• in addition to the final QoR-based design iterations, the design iterations also include local design iterations that select parameter values for a non-final stage of the design flow based on an intermediate quality of result (QoR) for that non-final stage.
