| Abstract: | This paper introduces the modern design circle of ASIC chip. A method of developing LGS, which is a logical simulation tool using C and the event-driven algorithm, is discussed in detail. The LGS is used on the n'etlist of digital circuit, which is described by Verilog HDL. A design can be envisioned as a hierarchical composition of modules. The paper describes the event-drive algorithm and some technical field when implemented. It also introduces the application of object orient technology in developing EDA (Electronic Design Automation) tools. At the end of the paper, an example of LGS simulation verification on a multiplier circuit design is given. |
