The Direct Numerical Simulation (DNS) of the transition process in a supersonic boundary layer from the laminar to the turbulent state significantly challenges existing numerical codes. High-order accurate methods are commonly used to improve the accuracy of simulations and thus reduce the number of required grid points. In this paper the development of a high-order code which is tailored towards stability and nonlinear transition simulations over a circular cone is discussed. A thoroughly conducted validation is presented. In particular, small amplitude disturbances are introduced to study the linear wave amplification (eigenbehavior). The results are compared to Linear Stability Theory (LST). Moreover, a three-dimensional stability diagram - in the downstream-frequency-azimuthal mode domain (Rx - F - k) - is extracted from these calculations and analyzed. Finally, the possible occurrence of oblique breakdown is highlighted by performing simulations with continuously forced finite{amplitude disturbances.
