Development of step motor controller IP core with trapezoidal velocity planning

This article first proposes a problem encountered in the project and the feasibility of solving it using FPGA. Then speaks the theory of velocity planning with trapezoidal curve and control strategy. Final details the implement of hardware and software of the step motor controller IP core, include the implement of hardware logic and the code writing of drive file and the package of driven functions. Additionally, verification is very important in the design of IP core. In Quartus II 6.0 development environment, the IP core passed the test and functional verification.
