这里以简单的3-8译码器和8-3编码器为例: 8-3编码器程序: 1)利用for循环 1 module encoder8_3(a,out,none_on); 2 input [7:0]a; 3 output [2:0]out; 4 output none_on; 5 reg [2:0]out; 6
只有for-loop语句是可以综合的。 14、设计时序电路时,建议变量在always语句中赋值,而在该always语句外使用,使综合时能准确地匹配。建议不要使用局部变量。 15、不能在多个always块中对同一个变量赎值 16、函数 函数代表一个组合逻辑,所有内部定义的变量都是临时的,这些变量综合后为wire。
Write code for a parallel encoder and a priority encoder. What is the difference between === and == ? What is defparam used for ? What is the difference between unary and logical operators ? What is the difference between tasks and functions ? What is the difference between transport and ...
如果描述一个编码器,在XILINX的XST综合参数就有一个关于优先级编码器硬件原语句的选项Priority Encoder Extraction. 而CASE语句是"平行"的结构,所有的CASE的条件和执行都没有“优先级”。而建立优先级结构会消耗大量的组合逻辑,所以如果能够使用CASE语句的地方,尽量使用CASE替换IF...ELSE结构。 #10:XILINX的底层可...
com/pConst/basic_verilog这里边包含了一些是veriog基础模块的设计，比如adder，fifo，Uart，encoder等。
