Modeling Content-Addressable Memory For Emulation

Abstract

Aspects of the invention relate to techniques for modeling content-addressable memory for emulation. An emulation device according to various embodiments of the invention comprises one or more memory modeling blocks reconfigurable to emulate a content-addressable memory or a random-access memory. The emulation device may be processor-based or FPGA-based. Each of the one or more memory modeling blocks comprises memory circuitry and a dedicated comparison unit configured to compare a search word or a portion of a search word received by the each of the one or more memory modeling blocks with data stored in the memory circuitry. The comparison unit may comprise a comparator and a register coupled to the comparator and configured to store matching data. The matching data may be unencoded matching data. A plurality of the memory modeling blocks may be programmable to emulate a single content-addressable memory.
