Phase diagram of layered superconductors is explored by Monte Carlo simulations of the 3-D uniformly frustrated XY model. Two regimes of behavior were observed depending on the anisotropy. At high anisotropy, the melting occurs as a strong first order phase transition and is accompanied by destruction of vortex lines and disappearance of superconductivity along the field direction. At low anisotropies, melting is shallow and the vortex crystal melts into a liquid of vortex lines with superconductivity along the field direction.
