Integrated circuit architectures with heterogeneous high-speed serial interface circuitry
An integrated circuit device such as a programmable logic device (“PLD”) includes a plurality of blocks of legacy circuitry. These legacy blocks leave at least one corner of the device unoccupied by such legacy circuitry. This at least one corner is used for relatively newly developed circuitry so as to simplify and speed the design of relatively new circuitry, to avoid having to significantly redesign any of the legacy circuitry to give the device the capabilities of the new circuitry, etc. The relatively newly developed circuitry may be high-speed serial data signal interface (“HSSI”) circuitry that is capable of operating at serial data rates faster than any legacy HSSI circuitry on the device.
