Overview

Imperas OVPsim is treated here as the Imperas simulator/virtual-platform tool associated with Imperas RISC-V processor models. A MICRO 2021 related-work discussion describes Imperas Software Ltd. as a commercial company that develops virtual platforms supporting a range of instruction set architectures, including RISC-V. The same source states that Imperas claims support for step-and-compare simulation capability.

Licensing and model availability

The cited paper states that Imperas provides RISC-V core models under the Apache 2.0 license. It also notes, however, that the model is attached to the simulator, which the paper says is licensed under the OVP Fixed Platform Kit.

Comparison with Dromajo

The same related-work section contrasts the Imperas solution with Dromajo. According to the paper, Dromajo differs from the Imperas solution by supporting checkpoints, and by having the whole Dromajo project licensed under Apache 2.0.
