Despite the pressure for system engineers to simulate evry design, a simulation of high-speed, high-performance analog circuit cannot substitute for a quality prototype. A review of prototyping methods helps you choose a technique suitable for your design.
Analog designers use as many tools as possible to ensure that the final system design performs correctly. The first step is the intelligent use of IC macromodels, if available, to simulate the circuit. The second step is the construction of a prototype board to further verify the design. The final pc-board layout should as closely as possible duplicate the prototype layout.
Unfortunately, system designers ...
