Abstract
A configurable method and apparatus for implementing the various large memory instances commonly found in a user's design in a hardware logic emulation system is disclosed. No external boards or systems are required to implement typical memory instances. The method and apparatus sorts the memory instances in the user's input design, packing as many memory instances as possible into a physical RAM on the emulation boards. The method also counts the number of physical RAMs necessary to implement the plurality of memory instances. The method maps the memory instances into physical RAMs, and routes the address, data and control signals and controller circuit into a programmable logic chip.
