This paper deals with the design of a MOD-6 synchronous counter using VHDL (VHSIC Hardware Description Language). The VHSIC stands for Very High Speed Integrated Circuit. Using this approach, the behaviour of the counter is the most important aspect The following are not usually synthesisable, except as part of a constant expression: exponentiation (**), division by other than 2, mod, rem.

Posted 1/12/09 4:23 AM, 12 messages The SPI master and SPI slave have been implemented using VHDL 93 and are applicable to any FPGA. The SPI master and SPI slave controllers support only SPI mode 0 (CPOL=0, CPHA=0)! The SPI master and SPI slave controllers were simulated and tested in hardware. Moving forward VHDL Mode is only tested on the latest GNU Emacs version (currently GNU Emacs 24).

Mod and Rem are not supported in Quartus II. Efficient design of multiply or divide hardware typically requires the user to specify the arithmetic algorithm and design in VHDL.

2.2 VHDL Modeling Concepts In this section, we look at the basic VHDL concepts for behavior al and structural mod-eling. This will provide a feel for VHDL and a basis from which to work in later chap-ters. As an example, we look at ways of describing a four-bit register, shown in Figure 2-1.

The mod operator represents clock or counter arithmetic.

The mod operator represents clock or counter arithmetic. VHDL also has a rem operator, whose definition is. a = (a/b)*b + (a rem b). Note that sign (a rem b) = sign (a) (opposite of mod) and. abs (a rem b) < abs (b) same as mod. The rem operator represents remainder after integer divsion. Mod and rem are different!

The entity section of the HDL design is used to declare the I/O ports of the circuit, while the description code resides within architecture portion. 2.2 VHDL Modeling Concepts In this section, we look at the basic VHDL concepts for behavior al and structural mod-eling.
