Cycle-Approximate Simulator

A Cycle-Approximate Simulator is presented in OpenVADL materials as an output or target in the OpenVADL tool flow. In the overview diagram, a VADL specification is processed by the VADL frontend into the VIAM intermediate representation, with architecture synthesis leading toward a cycle-approximate simulator; the same overview also shows QEMU simulation and hardware as other generated artifacts or targets.[1]
