Due to the present rapid development of mobile devices and Internet of Things (IoT) in the world, competition in the processing of semiconductor industry is even unavoidable. Looking at the international point of view, Taiwan is currently still keeping abreast of others in IC design and semiconductor industry. Following the fact that the semiconductor manufacturing process is progressing towards more complexity, one single chip can already accommodate a complete circuit system to contain both digital and analog circuits. Although the completion time of a project is affected by an IC workflow layout, and that the development of automatic software tools in the digital circuit sector has relatively matured, but the automated design tool of analog mixed-signal circuits has yet been popular due mainly to the very sensitive nature of analog circuits. This has caused a difficulty to develop an optimal common tool to use in all analog circuits. Thus, the analog circuit design has often become a bottleneck in the development of system on chip (SoC) on the entire analog mixed-signal circuits.
As layout configuring has a significant impact on the performances of analog and mixed-signal IC circuits, so the configuration of elements and blocks is particularly important. Furthermore, a need to consider a number of special layout configuration restrictions to obtain a high-efficiency circuit layout has resulted in the domination of analog and mixed-signal circuit layout been manually done by the engineers. Although manual layout is helpful for being able to take everything into account, but a considerable time is needed to complete the entire design. So, an auxiliary design tool is indispensable to help speed up the entire design process. In this study, an automated layout generator was built to serve as a test circuit for a radio frequency pickup device.
