This calculator contains a number of "rule of thumb" calculations useful in initial Signal
Integrity and Power Integrity analysis and design. As is strongly preached in the SI/PI
world, full simulation is strongly recommended for a true analysis of a design. However,
for early design stages, for answering a quick "swag" question, or for impressing your
peers with a quick response, this calculator can give you a ballpark answer.
Note: this was developed using Visual Studio 2015 and is therefore PC based. To run on a Mac you'll likely need some form of Windows emulator. |
