Fast Models Reference Manual - ARM Information Center

Accuracy and Functionality2.1 Model Capabilities OverviewFast Models attempt to accurately model the hardware, but compromises exist between speedof execution, accuracy and other criteria. This means that a processor model might not beexpected to match the hardware under certain conditions.For a detailed description of timing, bus and cache modeling limitations see Functional cachesin Fast Models on page 2-3 and How Accurate are Fast Models? on page 2-5.2.1.1 What Fast Models can doFast Models do:• Instruction accurate modeling• Correct execution of architecturally-correct code.2.1.2 What Fast Models cannot doFast Models cannot be used to:• Validate the hardware• Model unpredictable behavior• Model cycle counting• Model timing sensitive behavior• Model SMP instruction scheduling• Model software performance• Model bus traffic.ARM DUI 0423N Copyright © 2008-2012 ARM.
