Method, system, and computer program product for implementing incremental placement in electronics design

A system for implementing incremental placement of an electronic design, comprising:

• at least one processor for performing a plurality of actions, the plurality of actions comprising:
• identifying an initial placement of the electronic design, in which the electronic design comprises a plurality of electronic components to be incrementally placed in the electronic design;
• determining a flow of the electronic design based at least in part upon the initial placement of the electronic design;
• determining a target location for at least one of the plurality of electronic components to be incrementally placed in the electronic design by using a grid morphing process;
• minimizing a perturbation, which is caused by incrementally placing the at least one of the plurality of electronic components, based at least in part upon predicting an impact of the act of incrementally placing the at least one of the plurality of electronic components;
• and
• legalizing a final placement of the electronic design based at least in part upon a result of predicting the impact of the act of incrementally placing the at least one of the plurality of electronic components.

A computer program product that includes a non-transitory storage medium usable by at least one processor, the non-transitory storage medium having stored thereon a sequence of instructions which, when executed by the at least one processor, causes the at least one processor to execute a method for implementing incremental placement of an electronic design, the method comprising:

• using the at least one processor for performing a plurality of actions, the plurality of actions comprising:
• identifying an initial placement of the electronic design, in which the electronic design comprises a plurality of electronic components to be incrementally placed in the electronic design;
• determining a flow of the electronic design based at least in part upon the initial placement of the electronic design;
• determining a target location for at least one of the plurality of electronic components to be incrementally placed in the electronic design by using a grid morphing process;
• minimizing a perturbation, which is caused by incrementally placing the at least one of the plurality of electronic components, based at least in part upon predicting an impact of the act of incrementally placing the at least one of the plurality of electronic components;
• and
• legalizing a final placement of the electronic design based at least in part upon a result of predicting the impact of the act of incrementally placing the at least one of the plurality of electronic components.
