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. |

6.1 Procedures We start our discussion of subprograms with procedures . There are two aspects to using procedures in a model : first the procedure is declared , then elsewhere the procedure is called . The syntax rule for a procedure ...
The actions of a procedure are invoked by a procedure call statement , which is yet another VHDL sequential statement . A procedure with no parameters is called simply by writing its name , as shown by the syntax rule ...
