The Student's Guide to VHDLElsevier Science, 1998. gada 1. janv. - 336 lappuses VHDL 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. This new book provides a tutorialintroduction to the fundamental modeling features of VHDL and shows how the features are used for the design of digital systems. 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. |

... clock input of type bit . When the clock changes from ' 0 ' to ' 1 ' , the data input is sampled , stored and transmitted through to the output . Let us suppose that the clock input must remain at ' 1 ' for at least 5 ns . Figure 3-9 is ...
... clock signal ( assuming T_pw is a constant that represents the clock pulse width ) : clk < = ' 1 ' after T_pw , ' 0 ' after 2 * T_pw ; If this statement is executed at simulation time 50 ns and T_pw has the value 10 ns , one transaction ...
