9// This driver supports the vci_sim_helper component, that is a pseudo hardware
10// component available in the SoCLib library, and providing a monitoring service
11// in a virtual prototyping environment.
12//
13// There is at most one such component in the architecture.

15// The SEG_SIM_BASE address must be defined in the hard_config.h file.
