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. |

00001111ZZZZ " - empty string If we need to include a double quotation mark character in a string , we write two double quotation mark characters together . The pair is interpreted as just one character in the string .
Bit Strings VHDL includes values that represent bits ( binary digits ) , which can be either O ' or ' l ' . A bit - string literal represents a sequence of these bit values . It is represented by a string of digits , enclosed by double ...
Or we can directly create an object of the standard - logic vector type : signal csr_offset : std_ulogic_vector ( 2 downto 1 ) ; String and Bit - String Literals In Chapter 1 , we saw that a string literal may be used to write a value ...
