IC的设计可以分为两个部分，分别为：前端设计（也称逻辑设计）和后端设计（也称物理设计），这两个部分并没有统一严格的界限，凡涉及到与工艺有关的设计可称为后端设计。(The design of IC can be divided into two parts: front-end design (also called logic design) and back-end design (also known as physical design). These two parts do not have a uniform and strict boundary, and the design related to process can be called back-end design.)

The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.
