Unary sign operators: + - 6. Multiplying operators… VHDL OPERATORS C. E. Stroud, ECE Dept., Auburn Univ. 1 8/06 Logic operators are the heart of logic equations and conditional statements AND OR NOT NAND NOR XOR XNOR there is NO order of precedence so use lots of parentheses VHDL provides some shift operators as well e.g. SLL (shift left logic) and SRL (shift right logic) etc. But these operations can be used with ‘bit_vector’ only, therefore these are not discussed in the tutorial. Further, we can use the concatenation operator for shifting operation as discussed in Section 3.9.4. VHDL provides predefined operators which are used as hardware modeling units.

Binary operators take an operand on the left and right. "result same" means the result is the same as the left 36 rows xnor has been added to the logical operators in VHDL-94. New shift and rotate operators are defined for one-dimensional arrays of bit or boolean: sll -- shift left logical srl -- shift right logical sla -- shift left arithmetic sra -- shift right arithmetic rol -- rotate left ror -- rotate right VHDL has a wide set of different operators, which can be divided into groups of the same precedence level (priority). The table below lists operators grouped … Table 6.1 VHDL Operators.

Use slicing and concatenation. The VHDL operators are rather self-explanatory. While relational operators are available for all predefined data types, the logical, shift and arithmetical operators may only be used with bit and numerical values, respectively. Logical Operators.

It is therefore preferable to use subtypes since they share the same operators as their base type. • Other relational operators than ’=’ and ’/=’ are dependant upon the order in the enumerated type.
