Abstract: A circuit for that includes isolation logic is disclosed. In one aspect, circuit comprises at least one input/output (I/O) cell, the I/O cell further including circuitry functions, isolation control logic, and a capability to receive power to the I/O cell from a power domain source. In a second aspect an integrated circuit comprises a physical layer (PHY) logic and at least one input/output (I/O) cell in communication with the PHY logic. The I/O cell capable of receiving power from a plurality of power domains. The I/O cell includes an isolation control logic and an I/O logic capable of receiving power from one power domain of a plurality of power domains, wherein the I/O logic and the isolation controller are arranged in communication through a level shifter for shifting power to maintain an active operation of the at least one I/O cell; wherein since the isolation control logic is within the I/O cell, only one active power domain of the plurality of power domains is required.

Abstract: The present invention provides for a method and circuit of an integrated circuit (IC) having dual row input/output (I/O). The circuit having a plurality of dual I/Os including an upper row of I/O and a lower row of I/O, with logic arranged in communication between the upper and the lower rows of the dual row I/O. The connectivity with the logic circuits of the present invention therefore provides for improving reliability and performance through more similar and uniform pathway connections. Advantageously, the present invention also provides for the reallocation of valuable footprint space as the logic is embedded within the dual row I/O thereby creating additional footprint space for further performance and other beneficial gain where interconnects as between the physical layer (PHY) logic and I/O cells are generally similar in length.

Abstract: An improved approach is described for allowing designers to identify and utilize suitable IP for an electronic design. An architecture is provided that includes an IP portal and/or chip estimator to identify suitable IP from a catalog of IP, which is integrated with a hosted design environment to use and test that IP for the user's specific electronic design. An authorization mechanism may be used to control access to the IP from the IP catalog. This approach greatly enhances the probability that IP suppliers will be successfully connected with the target consumers of those IP blocks.

Abstract: Apparatus and method aspects for power gating of an integrated circuit (IC) include providing at least one I/O power pad of an IC with a switch arrangement. The at least one I/O power pad is utilized to control a power signal transfer to at least a portion of the IC.
