Interactive Model-based Resource Analysis for Systems Engineers
summary
Claim: an MPS-based tool called Simbench runs a discrete-event warp simulator (x‑warp/Extend on the JVM) to give spreadsheet‑like, immediate feedback on resource and timing tradeoffs. The demo models an infotainment startup where a 0.8 MB image load plus 17 ms init and dozens of parallel components misses a 1200 ms graphics‑available requirement by ~105 ms until an artificial dependency reduces parallel startup work; adding a second CPU cuts HMI startup from ~9 s to ~4 s. Reality checks compare simulator timestamps to real logs (example: real KPI ~10.5 s, simulator faster).
