Verilog: Reg is not declared Here is the declaration of the reg assignment reg [5:0]R = {bi7 ,[15:11]RGB}; //bi7 is a parameter but at the last line of the module i get this error where it points at the same reg assignment. In verilog, you can only assign a value to areg...
解析:不能在两个以上always内对同一变量赋值,这个细节一般看书看资料会看到,但是编程时,就是没想到。 2.Error (10158): Verilog HDL Module Declaration error at clkseg.v(1): port "XXXX" is not declared as port 解析:大意了,端口类型还没定义啊! 3.Error (10110): variable "en" has mixed blocking...
将module operation1(sum1,sum2,mult1,A,B,C,D,E); 改成module operation1(A,B,C,D,E);

4.Error (10161): Verilog HDL error at clkseg.v(36): object "count" is not declared 解析:这个错误应该很明显啦,只要能读得懂。 5.Error (10170): Verilog HDL syntax error at clkseg.v(37) near text "***"; expecting ";" 解析:意思应该也很简单,就是检查的时候要细心点。 6.Error (10171...
is high forces q to remain at 0. This condition may or may not be correct depending on the actual flip flop. However, this is not the main problem with this model. Notice that when reset goes low, that set is still high. In a real flip flop this will cause the output to go to ...
