UVM - 错误 - ：接近＆＃34;（＆＃34 ;:语法错误，意外＆＃39;（＆＃39;，期待IDENTIFIER或＆＃39; =＆＃39;

Question

我创建自己的宏文件：

`ifndef MY_MACROS_SV
`define MY_MACROS_SV

// MACRO: 'my_fatal_err
// calls uvm_fatal in case the assertion is not correct
`define my_fatal(condition, msg)\
   assert (condition) else\
`uvm_fatal("FATAL ERROR", msg)

`define add_rand(mem_type, mem) \
  begin \
   case (mem_type) \
     "int": add_rand_int(mem); \
     "bit": add_rand_bit(mem); \
     default: `uvm_fatal("FATAL ERROR", "type is not supported") \
    endcase\
  end

`endif  //MY_MACROS_SV

我收到以下错误：

** at .. \ sv \ tx_transaction.sv（21）：near＆＃34;（＆＃34 ;:语法错误，意外＆＃39;（＆＃39;，期待IDENTIFIER或＆＃39; =＆＃39;

tx_transaction.sv中的第21行：

  add_rand_macro();

add_rand是一个在base_transaction中定义的函数（tx_transaction扩展它）：

class base_transaction extends uvm_sequence_item();

   int rand_int_list [];   
   bit rand_bit_list [];


   bit [31:0] data [$];

   //add to list functions
   function void add_rand_int(int mem);
      rand_int_list.push_back(mem);      
   endfunction: add_rand_int
   ......
endclass: base_transaction

tx_transaction的代码：

class tx_transaction extends base_transaction;
   bit [15:0]  data_xi;
   bit [15:0]  data_xq;
   int mem_int;  //TODO- delete

   //uvm_object_utils\
   `uvm_object_utils(tx_transaction)

   //constructor
   function new(string name = "tx_transaction");
      super.new(name);
   endfunction: new

   function void add_rand_macro();
      `add_rand("int", mem_int)
   endfunction: add_rand_macro

   add_rand_macro();

   //TODO - DELETE
   function void foo();
      $display("rand mem int: %d", mem_int);
   endfunction: foo

endclass: tx_transaction

Answer 1

由于宏扩展为case语句，因此必须从类中的函数内部调用它：

function ...

    ...
   `add_rand("int", mem_int)   
    ...

endfunction

更新：确保使用分号结束function声明：

function void add_rand_macro();
    `add_rand("int", mem_int)
endfunction

更新：你不能在课堂上调用add_rand_macro函数;它必须在另一个函数内调用。
