If you want a count of then number of elements greater than 5, then you need to write y=numbers.sumwith(int'(item>5)); That's because the type of item>5 is a 1-bit expression, and sum of 1-bit expressions is a 1-bit result. 也就是说,在例子中,Item > 7表达式是个1位的表达式...
item:0求和,这个表达式的结果是item(如果大于x)或者0(如果不大于x) array.sum with (item), 对item求和,结果数据类型和item一致 array.sum with (int'(item)), 对int'(item)求和,即item转为int型后求和,结果数据类型也和表达式表达的数据类型即int型一致 array.sum with ((item >x) * item), 对表达式...

I'm trying to sum array values using System Verilog. My data are declared like this: reg signed [23:0] n2 [31:0]; reg signed [15:0] w2 [195:0]; w2is a reg with values stock in it. for(int i2=0; i2<32; i2++) begin ...
