TABLE OF CONTENTS The best way to escape from a problem is to solve it.
Alan Saporta
The design is built. The packets are defined and ports are configured. So what are you waiting for? Click the Start Simulation button and go. No, wait! You should know just a few more things. In this chapter you will learn the options that need to be set up before simulation starts. You will learn how to increase simulation rate to run faster than the network wire rate, how to log simulation results, and how to use startup scripts. After starting simulation, you will learn the basic debug views and techniques for exploring the state of your application while it is simulating.
For a simplified first simulation experience, let's take a look at another application, IPV4 ingress, in your SDK directory tree that you copied from the tools and applications CD-ROM. To get a copy, refer to this book's Web site, listed in "References."
\src\applications\ipv4forwarder\4gb_ethernet\ingress
This application handles IPV4 over Ethernet. No frills. No IPV6, tunneling, or extra decaps or encaps.
You could start simulating now using the default settings. However, it is useful to control certain simulation settings before packets start to flow. For example, you can elect to save the packets received or transmitted by the network processor. You can send in a fixed number of packets, or you can stop the simulation after a fixed number of packets have been received or transmitted. You can automatically run initialization scripts...
