Abstract: Exemplary embodiments include a method for modifying a circuit synthesis flow having automated instructions, the method including receiving circuit design input for a circuit design, receiving custom specifications to the circuit design input, synthesizing high level logic from the circuit design input, placing logic on the circuit design, refining the circuit design and generating a circuit description from the circuit design.

Abstract: A method for routing-based pin placement is provided and includes receiving a logical description of a macro of a partitioned circuit with connectivity information and a physical outline, generating an abstracted shape as an abstraction of a generic shape of a pin for providing a connection to the macro in accordance with the connectivity information as a shape conforming to dimensions of the macro, providing a routing tool with freedom to route a net for connection to the pin toward any part of the abstracted shape of the pin to create a routed net and identifying a location where the routed net crosses the physical outline as a chosen location for the pin.

Abstract: Exemplary embodiments include a computer implemented method for large block and structured synthesis, the method including determining initial design data from starting points for a synthesis flow, receiving user-directed structuring is incorporated into the synthesis flow, applying logical synthesis on the initial design data, applying a physical design on the initial design data, determining whether circuit design parameters have been met and in response to circuit design parameters not being met, adjusting the circuit design parameters.
