There are examples in which it might be useful to combine two or more conditional operators in a single assignment. Consider the truth table below. The truth table shows a 2-input truth table. You need to know the value of both r_Sel[1] and r_Sel[0] to determine the value of the ...
Vectorgates 位操作符与逻辑操作符(Bitwise vs. Logical Operators) 前面,我们提到了各种布尔操作符有位操作符和逻辑(bitwise and logical )操作符(例如,normgate ),当使用向量时,这两种操作符类型之间的区别变得很重要。两个(N-bit)向量之间的按位运算对向量的每个位重复运算并产生(N-bit)输出,而逻辑运算将整个...
Operands are compared bit by bit, with zero filling if the two operands do not have the same length Result is 0 (false) or 1 (true) For the == and != operators, the result is x, if either operand contains an x or a z
布尔表达式(Boolean expression)是由变量、常量(0-假和 1-真)和逻辑运算符(variables, constants (0-false and 1-true) and logical operators)组成的表达式,结果为真或假( true or false.)。 布尔函数是布尔表达式的代数形式。n 个变量的布尔函数由 f(x1, x2, x3….xn) 表示。通过使用布尔定律和定理,我...

Module instances are also examples of synthesizable RTL statements. However, one of the reasons to use synthesis technology is to be able to describe the design at a higher level of abstraction than using a collection of module instances or low-level binary operators in a continuous assignment. ...
What is the difference between bit wise, unary and logical operators? What is the difference between task and function? What is the difference between casex, casez and case statements? Which one preferred-casex or casez? For what is defparam used?
