The authors present FERRARI, a fault and error automatic real-time injector, which can evaluate complex systems by emulating most hardware faults in software. The current version of FERRARI runs on SPARC workstations, in an Xwindow environment. The motivation, methodology, design, implementation, and evaluation of FERRARI are presented. The techniques used to emulate permanent faults and transient errors in software are described in detail. Experimental results are presented for several error detection techniques. They demonstrate the effectiveness of FERRARI in its role as a fault and error injector.>
