2 Concept ( Tools • Specification ( Tools + Design Stages ( Tools • Implementation ( Tools Figure 1-1. A nominal, multi-stage development process From that beginning, we have progressed to the point where the EDA community at large, including both users and developers of the tools, are interested in more unified environments. Here, the notion is that the tools used at the various stages in the development process need to be able to complement each other, and to communicate with one another efficiently using effective file exchange capabilities. Furthermore, the idea of capturing all the tool support needed for an EDA development into a unified support environment is now becoming a reality. This reality is evidenced by some of the EDA suites we now see emerging, wherein several tool functions are integrated under a common graphical user interface (GUI), with supporting file exchange and libraries to enable all tool functions to operate effectively and synergistically. This concept, which we illustrate in Figure 1- 2, is the true future ofEDA.
Product Description
Using WAVES and VHDL for Effective Design and Testing The proliferation and growth of Electronic Design Automation (EDA) has spawned many diverse and interesting technologies. One of the most prominent of these technologies is the VHSIC Hardware Description Language, or VHDL. VHDL permits designers of digital modules, components, systems, and even networks to describe their designs both structurally and behaviorally. VHDL also allows simulation of the designs in order to investigate their performance prior to actually implementing them in hardware. Having gained the ability to simulate designs once encoded in VHDL, designers were naturally confronted with the issue of testing these designs. VHDL did no...
