In this paper, we present the design and simulation of a Stereo Crystal Electromagnetic Calorimeter (SCECal) for the Circular Electron Positron Collider (CEPC). The SCECal is based on a novel stereo crystal configuration that obtain the 3D position resolution of the calorimeter from 2D readout. We analyze the performance of the SCECal using simulations with BGO crystals and evaluate the energy and 3D positioning resolution for different types of particles. Additionally, we investigate the separation power between photons and pions using a simplified reconstruction method. The results show promising energy and position resolution as well as efficient particle separation capabilities.
