verilog编程建议 1、不使用初始化语句; 2、不使用延时语句; 3、不使用循环次数不确定的语句,如:forever,while等; 4、尽量采用同步方式设计电路; 5、尽量采用行为语句完成设计; 6、always过程块描述组合逻辑,应在敏感信号表中列出所有的输入信号; 7、所有的内部寄存器都应该可以被复位; 8、用户自定义
verilog如何表示缺省的数字呢?比如case({op,funct,rt}){BEQ_op,6'bxxxxxx,5'bxxxxx}:ALUCode=alu_beq;{BNE_op,6'bxxxxxx,5'bxxxxx}:ALUCode=alu_bne;我想表示当funct和rt为任意值时,只要op=BEQ_op,则ALUCode=alu_beq.如何表示缺省的funct和rt呢?用x好像不行啊 答案 case(op)BEQ_op:ALUCode=alu...

道理也比较简单,那么我们如何用verilog HDL描述一个全加器呢?如下所示:,是一个1-bit的全加器 module fa(sum,c_out,c_in,x,y); //full adder input x,y,c_in; output sum,c_out; assign {c_out,sum}=x+y+c_in; endmodule 有了半加器和全加器,我们就可以组成各种各样的加法器了。
