This application note describes a parameterizable content-addressable memory (CAM), and is accompanied by a reference design that replaces the CAM core previously delivered through the CORE Generator™ software. The CAM reference design should be used for all new FPGA designs targeting Virtex®-6, Virtex-5, Virtex-4, Spartan®-6, Spartan-3, Spartan-3E, Spartan-3A, Spartan-3A DSP FPGAs, and newer architectures. All the features and interfaces included in the reference design are backward compatible with the LogiCORE™ IP CAM v6.1 core. In addition, because the reference design is provided in plain-text VHDL format, the implementation of the function is fully visible, allowing for easy debug and modification of the code.
