As noted before, one common use case for Simics is doing fault injection. Fault injection is typically added to an existing system without changing it, since the goal is to maintain a fundamentally fast simulator when not injecting faults. There are a range of mechanisms available in Simics to implement fault injection. This blog post will take a look at two such mechanisms and how they are used in the context of injecting faults on a serial port.
