The main task is translating the behavioraldescription of a digital system into the design of RTL(Register Transfer Level).
高层次综合也叫行为级综合，其基本任务是完成数字系统行为描述到寄存器传输级（RTL）描述的转换。

The controller is modeled as a hierarchical finite-state-machine from which a behavioral VHDL description is generated automatically. The device is prototyped using a FPGA-based emulating system.
