There are three possibilities for the transformation of an instruction. For each Verilog statement in the map at location $i$, the statement is either a load, a store or neither. The load or store is translated to the equivalent representation using the RAM specification and all other instructions are left intact. An example of the specification for the translation of the store instruction is shown below, where $\sigma$ is state register, $r$ is the RAM, $d$ and $c$ are the input data-path and control logic maps and $i$ is the current state. $n$ is the newly inserted state which only applies to the translation of loads. +The first step in proving the simulation correct is to build a specification of the translation algorithm.
