The Student's Guide to VHDLElsevier Science, 1998. gada 15. janv. - 312 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. 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 ...
