WebMemory Modeling. To help modeling of memory, Verilog provides support for two dimensions arrays. Behavioral models of memories are modeled by declaring an array of register variables; any word in the array may be accessed using an index into the array. A temporary variable is required to access a discrete bit within the array. WebFirst, make sure to put no path prefix on the filename inside your HDL: parameter HEX_PATH = "./"; // Set to local dir.
