Abstract: Aspects of the disclosure provide for eliminating or reducing uniquification of blocks in a chip-level graph of a computer chip, to reduce the size of the graph while still encoding block-specific information. For each group of blocks in the graph generated from a multiply-instantiated block (MIB), a block in the group is selected as a base block. The physical position of the base block is encoded in a reduced graph, and the physical positions of the remaining blocks are encoded as a linear transformation of the physical position of the base block across the face of the chip. Each group of blocks instantiated from the same MIB is represented as a single instance. The reduced graph can be fed into a device configured to perform a circuit component placement process, to identify the placement of circuit components for blocks in the chip in accordance with one or more objectives.

Abstract: Described is an integrated circuit (IC) that allows for communication between any input/output (I/O) pin and onboard peripherals. Accordingly, the resultant IC can be easily documented and connections between I/O pins and peripherals can be managed for each peripheral independently. The IC may include one or more sets of hardwired connections that provide a connection between of any I/O pin and any onboard peripheral. The hardwired connections may include the use of one or more crossbars. This increases the overall functionality and potential applications for an IC as the only limitation on peripheral connectivity is the number of I/O pins.
