The ease to learn how it works with all your circuit designs can be described as very easy (it isn't like learning new languages). It has become my workhorse in almost daily tasks; solving problems at different levels from schematic design through detailed physical testing simulations etceteraThe fact that you dont need other simulators such us SPICE or LTspice makes this program unique. I have used many analog tools but there was always something missing compared eith VSA which covers everything just right! You don’t want any additional hardware needed when designing using VSAs features - only good old pencil&paper drawings would do nowdaysIt also gives me real time visualization capabilities by means including 3D visuals so making sure i am not overlooking anything during layout phaseThis thing rocks. . I like the fact that you can create your own blocks to make the models more customized. It is easy to use with all kinds of technical knowledge. You also have a good user interface which is very clear. The tool does not support 3D model export in some formats (e.g. *.stl). We used it to simulate digital circuits and design FPGAs. We got our models exported as *.stl and we could upload them to our PCB manufacturer. This way the designers did not need any extra hardware.
