If I am not very wrong the firm behind electronic Workbench was acquired by National Instruments some time ago. And they changed name to Multisim.Hello, Can anybody direct me to a website to download the Electronic Workbench simulator program. Thanks
I agree.My view is that a good Spice analog simulator is a required tool to develop and optiminze an analog circuit design including looking at alternate designs and observing the effects of component tolerances, etc. Then you breadboard it for the final tweaking of the design. A simulator is an indespensable part of my design tools. Any electronic design engineer that graduates from college and isn't familiar with circuit simulation is seriously limited when it comes to analog circuit design.
So am I. And I would have given one of those same appendages for a calculator that could perform polar-rectangular conversions when I was in college. Doing that conversion on a slide-rule was a royal pain.I agree.
I'm old and retired. I designed and breadboarded a TON of circuits, some very high performance, in my career, including quite a few that didn't work. I would have given my left cojón for a simulator. It would have saved me a LOT of time.
The simulator is a great tool that you can't be without, but it is only useful when you have calculated the component values, voltages, and currents with a calculator. Going directly to a simulator can lead to some pretty bad circuits because simulators have a tendency to lie and it is hard to know what results to expect if you hanen't done the calculations. A simulator is invaluable for checking out circuit variations.My view is that a good Spice analog simulator is a required tool to develop and optiminze an analog circuit design including looking at alternate designs and observing the effects of component tolerances, etc. Then you breadboard it for the final tweaking of the design.

Of course. A simulator is not a substitute for doing the design calculations. But it's very useful for verifying a design's operation and catching design errors. Then you go to the breadboard. In most cases the breadboard will operate closely to the simulation.The simulator is a great tool that you can't be without, but it is only useful when you have calculated the component values, voltages, and currents with a calculator.

I am not surprised that if you work as an application engineer with a lot of feedback from customers that have problems simulating circuits (who are likely newbies, or not very good designers), then you likely would have a somewhat negative view of simulators. I think that's why Bob Pease had his bad opinion about them. But they are very useful for good engineers who do the paper design before simulation or do them somewhat interactively to optimize the design. You don't hear about those because they don't call you with problems. Obviously iterative design by simulator is not a valid design approach.I was talking to the new engineers who have a tendency to simulate prior to calculating. You may not think that this happens, but as an applications engineer I saw it at least every month. Both cases happen: the design works and the simulator doesn't or the sim works and the design doesn't.
