How to implement Content Addressable Memory in Stratix V FPGA

The modern FPGAs don't have CAM any more. You can emulate a CAM using a regular memory block, but of course it uses a lot more memory bits. You can have a look at pages 9.6 and over in the advanced synthesis cookbook (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/manual/stx_cookbook.pdf) for a way to implement it.
