Abstract

A method and system of dynamically selecting a memory read port are provided. In one form a method may comprises, in part, processing instructions in the emulation processors of a hardware functional verification system, storing output bits generated by the LUT in a plurality of storage elements, selecting between a plurality of previously-stored LUT output bits and the output port of the data memory, selecting one of the plurality of output bits stored in the storage elements, and sending the current data bit provided at the output port of the data memory to a selection circuit when previously-stored LUT output bits are provided. The disclosed systems and methods provide the ability all inputs to a LUT, even while a memory read port is occupied performing other operations during that emulation step, for example sending a value stored in the memory to another emulation processor using the selection circuit.
