#171082 - Useful Sometimes, It Depends... Responding to: ???'s previous message |
Here is an answer to one of your questions: "Why bread board....?": Because, like the other poster mentioned, simulated components are not always correct in their behavior or parameters. Additionally, there is the "real world" factor: an actual, live circuit can show unexpected, oddball, or otherwise overlooked operations that did not occur in the simulated domain. Overconfidence without testing is not a good thing. Once I worked with a guy who refused any 2nd opinion or real testing whatsoever design a Z80 microcontroller video board that "should have worked." It was "straightforward", being a stripped-down copy of the manufacturer's demo board. We ended up with a large box of expensive paperweights! I put a value on both simulation & prototyping, where feasible and of meaningful value. |
