verilog signed >>

在Verilog中，signed修饰符用于指示数据是有符号数。signed修饰符的作用并不是为了区分有符号数和无符号数的加法和乘法，而是决定了如何对操作数进行扩位。如果想将操作数作为有符号数来进行右移操作，可以使用$signed()函数来将操作数转换为有符号数类型。例如，Result = ($signed(operandB)) >>> operandA; 。在这个例子中，$signed函数将operandB转换为有符号数，然后进行右移操作。这样的操作将按照有符号数的方式进行扩位，在高位补符号位。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
