program可以看做是软件的部分,所以program中不能出现和硬件行为相关的语句,比如always、module、interface,也不能出现其他program的例化语句。program中可以发起多个initial块,也可以定义新的变量。 program的内部变量赋值方式,应该采用阻塞赋值(模拟软件行为),program内部在驱动外部的硬件信号时应该采用非阻塞赋值(硬件方式)。

35. Direct Programming Interface 需求 随着时代的发展,现在的芯片规模越来越大,哪怕模块级的验证环境也需要相当长的build时间,各种仿真工具也在改进编译和运行性能,还发明了增量编译。但无论如何增加features,turnaround的时间还是比较长,而且方法越复杂越容易出错。而DPI-C则比较简单,能够解决某些场景下的问题。
