Abstract: The plasma shape equilibrium and fitting code (EFIT) is the basis and important element of experimental advanced superconducting tokamak (EAST) superconducting Tokamak control system. The physics concept of EFIT code applied in Tokamak is described. This paper introduces the developing plan and main flow structure of EFIT code in EAST. And the composingof Green functions and the most important subroutine of equilibrium and fitting are analysed.Three main problems and their solutions of developing are described. The Green functions data and character parameters of plasma produced by code are analysed.
