The Student's Guide to VHDLVHDL is a language for describing digital electronic systems. A vital, efficient step in the system design process, VHDL allows for the design and simulation of a hardware system prior to it actually being manufactured. Offering the same clear, accessible style as The Designer's Guide to VHDL, The Student's Guide is designed as a main text for introductory VHDL courses, and as a supplementary text for courses that require VHDL-based project work, such as computer architecture, digital design, and digital logic courses. This new condensed text also serves as a quick, self-teaching guide for practicing engineers who need to learn only the basics of VHDL. |

case _ statement case expression is case _ statement _ alternative { . . . } end
case ; indicates that a case statement must contain at least one case statement
alternative , but may contain an arbitrary number of additional case statement ...
This value is then compared with the choice values in the case statement
alternatives to determine which statement to execute . An if statement ... Thus , we
can have a case statement that selects an alternative based on an integer value .
in previous alternatives , we can use the special choice others . ... operand : = 0 ;
end case ; In this example , if the value of operand is anything other than the
choices listed in the first and second alternatives , the last alternative is selected .
