如果您正在设计的嵌入式系统包含的软件与硬件一样多，您将需要建立一个系统级的技术规范，并采用统一的设计方法我们不想让一批硬件设计师在一个楼里忙碌工作，而软件设计师却在另一个楼里等待硅产品问世；我们需要能够并行设计硬件和软件的系统设计师。为此，您需要在高层次? If the embedded system you are designing contains as many pieces of software and hardware, you will need to establish a system-level specification and adopt a uniform design approach. We do not want to allow a group of hardware designers to be busy working in one building. Software Designers are waiting for silicon in another building; we need a system designer who can design hardware and software in parallel. To do this you need at a high level?
