A design starts in the mind of an architect, gets drawn on whiteboards as basic block diagrams that describe a system. Next, designers see what can be reused from older designs, schematics get drawn, parts are identified, from in-house libraries or from online vendors. If the available parts don’t match their requirement, librarians are asked to create or modify parts. Then checks and rules are run to ensure design integrity. Teams work together on a large design. Libraries are updated, flags go up on the designers’ screens telling them newer parts are available, or someone has made changes. They sync their changes. Different versions are maintained for the entire design or even the parts used. Variants are created for different costs or geographies. Finally, the logical design gets done and is converted to a netlist, and layout files are made. Routing and layout experts come into the picture and, ta-dah! the design is ready for fabrication.(read more)![]()
