`elsif D01 reg t01;2) `ifdef 宏名 (标识符) 程序段1 `endif 这里的 "宏名" 是一个Verilog HDL的标识符,"程序段"可以是Verilog HDL语句组,也可以是命令行。这些命令可以出现在源程序的任何地方。注意:被忽略掉不进行编译的程序段部分也要符合Verilog HDL程序的语法规则。Verilog `ifdef `elsif Example The following example has two display statements inside separate `ifdef scopes which does not have a default `else part to it So this means that by default nothing will be displayed If the macro either MACRO is defined,
