在Verilog HDL语言中运算符所带的操作数是不同的,按其所带操作数的个数运算符可分为以下3种。 单目运算符(unary operator):可以带一个操作数,操作数放在运算符的右边。 二目运算符(binary operator):可以带两个操作数,操作数放在运算符的两边。 三目运算符(ternary operator):可以带三个操作数,这三个操作数...
The order of the table tells what operation is made first, the first ones has the highest priority. The () can be used to override default. // conditional operator ?:, this example is an expression that implements min(a, 10)wireout;assignout = a >10?10: a;// if a==b then c=0...
