The SCAM is composed of three main blocks: the controller (SCAMC), the data repository (SCAMD), and the response block (SCAMR), as described in the first article of this series. In order to realize my design, I used ispLEVER Schematic Editor to prepare the logic circuit schematics for the building blocks of the SCAM. The process started with designing the basic cell types representing the bottom of the hierarchy. Figure 1 illustrates those hierarchy cells denoted by "cam_cell," "delimiter_cell," "tag_cell," and "control_cell." A symbol (representing a virtual logic device) was created for each cell type using the ispLEVER Project Navigator process, "Generate Symbolic Symbol" (see the right pane in Figure 1).
