Front End Design
As the critical part of ASIC backend design is automated, the front end design is becoming more and more important in ASIC design today. However for high performance and low power chips the back end also has enough complexities. Another upcoming area in VLSI front end is model driven development, where readymade models will be customized with few mouse clicks and will be instantiated in the design. The model get capability to generate the HDL codes.
