Arithmetic and logical binary operators in verilog
In other languages Add links. At each step arithmetic and logical binary operators in verilog this recursive calculation the logical bit-wise operation is performed on the result of a previous operation and on the next bit of the operand. Examples of using the reduction operators are in shown Example 6. The logical operators are used to connect expressions. Blocking assignments occur sequentially, and the code after the assignment will not execute until the assignment has occured.
Logical operators act on an entire value multiple bitsand treat the values of "zero" as being "false", and "non-zero" as being "true". All vacated bits are filled with zeroes. The bit-wise operators calculate each bit of results by evaluating the logical expression on a pair of corresponding operand bits. The arithmetic operators can be used with all data types.
Examples of using the bit-wise operators are shown in Example 5. Division is a particularly complicated operation, and most programmable chips do not have dedicated divider modules. The modulus operator is not allowed for real data type variables. The result for these operators is 0 when false1 when trueand unknown x - when ambiguous.
In practice, the division and modulus operators are typically only usable in simulation, arithmetic and logical binary operators in verilog synthesis. All vacated bits are filled with zeroes. If the expression that specifies the number of bits to shift right operand has unknown x or high-impedance z value, then result will be unknown. The operation is repeated for all bits of the operand.
