Can Cx51 simulate 8051 chip (memory, port,..)? If possible, can it simulate with asm code?? If impossible, does keil have tools to do this? Thanks.
"It's the first time I use Keil's products ... can you give me introductions" Start by reading the uVision Getting Started Guide, and work through the example projects in it. This will give you a proper introduction to the tools, what they do, and how to use them. There is also an introductory video presentation on the free CD: https://www.keil.com/demo/cdrom.asp The Keil tools are not trivial (no software development is); you cannot expect to just install the tools and then dive straight in!
