ERROR: [VRFC 10-2991] 'if_space' is not declared under prefix 'genloop' [...] 同样代码在Questasim/Modelsim中通过且行为正确。 以上设计代码在参数化设计中有使用,例如: 注意下面例子中不能使用genloop[i].param1,因为verilog中if语句会创建新的命名空间,这样使用会报错找不到param1;lacalparam换成param...

If there are variables used in the model, such as real and integers, these need to be declared before use. Variable names must start with a letter or _, and are case sensitive. The analog begin line is where analog behavior begins. Often, this section is where voltage and currents from...
