一个简单组合逻辑加法运算 不知为何报错 多谢大家wire [4:0] s_vertical_base_address;
wire [4:0] s_block_vertical_count;
wire [4:0] s_vertical_address;
always @ (s_vertical_base_address or s_block_vertical_count)
s_vertical_address = s_vertical_base_address + s_block_vertical_count;
报错 Procedural assignment to a non-register s_horizontal_address is not permitted, left-hand side should be reg/integer/time/genvar
wire [4:0] s_block_vertical_count;
wire [4:0] s_vertical_address;
always @ (s_vertical_base_address or s_block_vertical_count)
s_vertical_address = s_vertical_base_address + s_block_vertical_count;
报错 Procedural assignment to a non-register s_horizontal_address is not permitted, left-hand side should be reg/integer/time/genvar
将always块改为assign s_vertical_address = s_vertical_base_address + s_block_vertical_count;
或
将第二句声明改为reg [4:0] s_vertical_address;
RE: 组合逻辑报错
感谢！
如果要用always实现组合逻辑，必须定义为reg。报错部分提出的就是这个问题
常识性错误。
继续努力
学习英文啊
