Register pull-out for sequential circuit blocks in circuit designs

摘要

Register pull-out for sequential circuit blocks may include determining, using computer hardware, a net of a circuit design having a driver that is a macro circuit block driving a plurality of loads and determining, using the computer hardware, a placement difficulty of the net based upon a type of the driver and number and type of the plurality of loads. In response to determining that the placement difficulty of the net exceeds a threshold placement difficulty, the computer hardware is capable of modifying the circuit design by pulling a register from the driver to a location on a device external to the driver and changing internal logic of the driver based upon the pulled register.
