Pánek et al., Czech J Phys 56, B125, 2006]. at IPP Prague.  MHD equilibrium is a fundamental property of the tokamak plasma, whose knowledge is required for many diagnostics and modelling tools. Proper benchmarking and validation of equilibrium tools is thus key for interpreting and planning tokamak experiments. We present here benchmarks and comparisons to experimental data of the EFIT++ reconstruction code [L.C. Appel et al., to be submitted to Nucl. Fusion], EPS 2006, P2.184],  the free-boundary equilibrium code FREEBIE [J.-F. Artaud, S.H. Kim, EPS 2012, P4.023], and a rapid plasma boundary reconstruction code VacTH [B. Faugeras et al., PPCF 2014, accepted]. We demonstrate that FREEBIE can calculate the equilibrium and corresponding poloidal field (PF) coils currents for given plasma parameters. consistently with EFIT++ reconstructions from experimental data.  Both EFIT++ and VacTH can reconstruct equilibria generated by FREEBIE from synthetic synthetic, optionally noisy  diagnostic data (including an artificial noise) and hence might be data. Hence, VacTH is  suitable for real-time control. Optimum reconstruction parameters are estimated; in addition, possible enhancements using more diagnostics are discussed and simulated using synthetic diagnostics. FREEBIE can also calculate the temporal evolution of the poloidal field coils currents for a whole plasma scenario. estimated.  \end{abstract}      Binary files a/JUrban_SOFT2014.pdf and b/JUrban_SOFT2014.pdf differ
