Chapter 21
Examples
The most productive way of learning a simulation tool such as Eldo is to get ‘hands-on’
experience by sitting at a terminal and working through, stage by stage, a number of practical
circuit simulation examples.
The examples cover a wide range of simple but concise circuit applications. They should be of
interest not only to the novice user, but also to the experienced user wishing to learn more about
specific simulation techniques within Eldo. Upon completion, a wide range of techniques
needed to perform efficient and productive analysis using Eldo should have been learnt.
A summary of the circuits used in this chapter, together with a brief description of the Eldo
subject areas dealt with are listed in Table 21-1. Listings for these examples may be found in the
following subdirectories included with your software:
