IEC vs IEEE Standard

Question asked by kirbstone on Nov 5, 2014


This question may not be in the correct location and if not please move it to maybe the general questions asked location?


I'm interested in finding out which standard IEC vs IEEE most people are using when designing symbols for DxDesigner PADS and Expedition.

We have been following the IEEE standard for many years but are being asked to start using the IEC standard. When we try to verify a symbol against the datasheet following the IEC standard it becomes very complicated. The images and pin text on the datasheets from the vendors seem to be following the IEEE standard.

Are there cheat sheets that help people understand the IEC standard? Is the IEC standard mostly a European standard and the US is starting to adopt it? Are the IEEE standards slowly converting over to IEC standards?

I've also noticed Mentors library seems to have a combination of both IEC and IEEE symbols.

Your comments on this subject would be appriciated.
