  • Patent number: 10977408
    Abstract: Embodiments disclosed herein describe systems, methods, and products for concurrently placing and optimizing input-output (IO) pins and internal components of an integrated circuit (IC) design. In an illustrative process flow, the computer (executing an illustrative EDA tool) may import the IC design and unplace the IO pins of the imported IC design. The computer may set one or more constraints for the IO pins with more degrees of freedom than the conventional pre-fixed locations. The computer may then concurrently place the IO pins and the internal components such that the IO pins obey the one or more constraints. The computer may iteratively optimize the placement of the IO pins and the internal components while ensuring that the one or more constraints are not violated.

  • Patent number: 10902174
    Abstract: Various embodiments provide for modeling a power and ground (PG) mesh for a circuit design placement process. For some embodiments, a reference PG mesh can be used to generate a PG mesh model for a circuit design. A PG mesh model can be generated for a circuit design by calculating how much routing resource is occupied by the reference PG mesh of the circuit design, and the resulting PG mesh model can be applied to the circuit design by removing a similar amount of routing resource from the circuit design during a placement circuit design flow. Additionally (or alternatively), a PG mesh model can be generated to comprise a set of metal obstructions that correspond to each macro of the circuit design, and the PG mesh model can be applied to the circuit design by adding the metal obstructions to one or more metal layers of the circuit design.
