With 55-port input data, the value returned by 'rationalfit' is a 55x55 array of fit objects. As shown in the error message above, the first input argument of 'writeva' must be a scalar, not a 55x55 array. The

错误原因是是不能将count综合成一个FF或者latch，首先你需要知道FF或者锁存器的结构，然后你才能真正明白这个错误的原因。其实就是你在always进程中的描述有点儿问题。下面是推荐代码：module counters(clk,reset,enable,done);input clk; //时钟信号 input reset; //low is active,asynchronous ...
module fff(outcall_1,call_1,record1,record2,pos1,pos2);input outcall_1;output call_1;reg call_1=0;reg[1:0] num1,num2;input[3:0]record1,record2,pos1,pos2;always@(posedge outcall_1 or negedge record1[0] or negedge record2[0] ) //如果在一楼 begin if(!record1...
Icarus Verilog is intended to compile ALL of the Verilog HDL as described in the IEEE-1364 standard. Of course, it's not quite there yet. It does currently handle a mix of structural and behavioural constructs. For a view of the current state of Icarus V
帮我看下下面verilog程序，count赋值不进去，显示 <count> does not match a known FF or Latch ...
