In this paper we propose an extension to the MagicGrid framework to support virtual prototyping for early system performance Validation & Verification (V&V). Model-Based Systems Engineering (MBSE) is at a maturity where V&V of system performance is expected to be automated for mature analysis. However, current practices do not adequately cover nor describe how this can be enabled in standard MBSE processes given that SysML models are used as the baseline for the system descriptions and knowledge capture. Therefore we propose an extension of the industrially accepted MagicGrid framework to cover virtual V&V in a tool and process agnostic method, supporting practitioners to develop and use models in MBSE for this purpose without a specific vendor or method lock. The framework extension is discussed for each new cell in the grid, and we provide guidelines and best practice discussions for how V&V should be enabled for each cell. At each abstraction stage of the grid we provide practical examples and demonstrate how simulation can be achieved, either through simulating/analysing SysML directly or through (Co-)simulation. Guidelines and anti-patterns are provided to help practitioners apply the paper contents in more specific scenarios through pragmatic heuristics.
