Methods and computer readable media for software modeling. The method comprises accessing one or more software execution traces describing execution times of tasks within software executed on a target platform. The method also comprises generating a workload model of the software based on the one or more software execution traces of the software executed on the target platform. The workload model describes tasks of the software and workloads on the target platform associated with the tasks of the software.

Generation of workload models from execution traces

Systems and methods for simulation with dynamic run-time accuracy adjustment. In one embodiment, a first portion of a sequence of software instruction is simulated by a first simulation model, during a simulation. During the same simulation, a second portion of the sequence is simulated by a second simulation model. State information may be transferred from the first simulation model to the second simulation model. A change from simulating the first portion of a sequence of software instructions by the first simulation model to simulating the second portion of the sequence by the second simulation model may be made responsive to a computer-based determination of an advantage obtained by the change.

Simulation with dynamic run-time accuracy adjustment

Systems and methods for run-time switching for simulation with dynamic run-time accuracy adjustment. In one embodiment, a computer implemented method performs a simulation of a computer instruction executing on a simulated hardware design by a first simulation model, wherein the first simulation model provides first timing information of the simulation. The first timing information is stored to a computer usable media. A pending subsequent simulation of the instruction is detected. Responsive to the presence of the first timing information in the computer usable media, the computer instruction is simulated by a second simulation model, wherein the second simulation model provides less accurate second timing information of the simulation than the first simulation model. The simulation run time information is updated for the subsequent simulation with the first timing information.
