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.

... reset to zero . The output stays at zero as long as the reset input is ' 1 ' and resumes counting on the next clock transition after reset changes to ' 0 ' . The revised entity declaration , shown in Figure 3-4 , includes the new input ...
... reset = ' 1 ' ; count_value = ( count_value + 1 ) mod 16 ; count < = count_value ; end loop ; -- at this point , reset = ' 1 ' count_value : = 0 ; count < = count_value ; wait until reset = ' 0 ' ; end loop ; end process incrementer ...
