For global or localstaticvariables, they areempty-initialized Intuitively, such variables are initialized to some kind of "zero". This is calledzero-initializationin C++. 使用未初始化的变量的值是未定义行为。 [Best practice]Always initialize the variable. const变量在初始化后不能修改。但是C语言可以...
整个SystemC仿真的执行过程由SystemC调度器控制,Initialization是SystemC调度器执行的第一步。 SystemC核心语言库定义了三种进程: SC_METHOD、SC_THREAD和SC_CTHREAD。在初始化阶段,缺省情况下每一个进程都被执行一次,THREAD进程被执行到第一个wait()语句。
