The case statement and the if statement are both examples of sequential statements in SystemVerilog. In the rest of this post, we talk about how we use both of these statements in SystemVerilog. We then consider a short example for both of these constructs to show how we use them in prac...
马上HDLBits-SystemVerilog版本也开始准备了,基本这一部分完成后就开始更新~ 决策语句(Decision statements)允许程序块的执行流程根据设计中信号的当前值分支到特定语句。SystemVerilog有两个主要的决策语句:if…else语句和case语句,使用关键字case、case…inside,casex和casez。 介绍 if-else语句对表达式求值并执行两个可能...

The first part of the expression evaluates to false. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error. Tips You can nest any number ofifstatements. Eachifstatement requires anendkeyword. ...
if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks...

第5章 语句 简单语句(Simple Statements) 如果在程序的某个地方,语法上需要一条语句但是逻辑上不需要,则应该使用空语句(null statement)。空语句中只含有一个单独的分号;。 使用空语句时应该加上注释,从而令读这段代码的人知道该语句是有意省略的。 多余的空语句并非总是无害的。 复合语句(compound statement)是...
The output is a vector of logical values. Theanyfunction reduces such a vector of logical values to a single condition. In this case,B = any(A < 0.5)yields logical1. This makesanyparticularly useful inifstatements. if any(A < 0.5) ...
