1、在verilog中有时会用signed修饰符来修饰定义的数据,运算的时候也会用$signed()任务来强制转换数据,那么signed的修饰是为什么呢,是为了区分有符号数和无符号数的加法和乘法

相信各位小伙伴,都能理解该仿真结果的产生,但是可能有的小伙伴会有疑问,为什么signed_vector的-128结果中间有很多空格?你真的仔细,先为你竖起大拇指,接下来我们就讲解一下为什么输出结果会是这样。

在数字电路中,出于应用的需要,我们可以使用无符号数,即包括0及整数的集合;也可以使用有符号数,即包括0和正负数的集合。在更加复杂的系统中,也许这两种类型的数,我们都会用到。

没想到啊没想到啊,有一天会被浓眉大眼的assign背刺!想当年在always消失术里,在X态分析里,在xprop平替策略里,把assign捧的这么高,优点说了800多项,然后今天一仿真出bug了?!

如果一个表达式同时包含signed和unsigned整型,signed会提升为unsgined,可能会隐藏一些意想不到的错误,特别是用在比较运算时
