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. |

Booleans One of the most important predefined enumeration types in VHDL is
the type boolean , defined as type boolean is ( false , true ) ; This type is used to
represent condition values , which can control execution of a behavioral model .
For or and nor , the right - hand operand is not evaluated if the lefthand is true .
VHDL - 87 The logical operator xnor is not provided in VHDL - 87 . Bits Since
VHDL is used to model digital systems , it is useful to have a data type to
represent bit ...
In this example , the first condition is evaluated , and if true , the statement after
the first then keyword is executed . If the first condition is false , the second
condition is evaluated , and if it evaluates to true , the statement after the second
then ...
