In a semiconductor company, the ASIC engineers design the hardware, and the hardware specification is distributed to other teams for hardware validation, embedded software development, and data-sheet documentation. Unfortunately, no standardized tools to document and distribute the specification exist. ASIC engineers often use common tools, such as Microsoft's Word or Excel, or even a plain text editor; these "tools" have many shortcomings when used to create a hardware specification.
First, these tools cannot easily convey the structure of a hardware specification. The hardware design of a chip typically has a tree-like hierarchy--the chip has several logical blocks, each block contains many registers, and each register has multiple bitfields, as shown in Figure 1.
