Dear all,

I want to show the accuracy of a circuit against process variation by histogram, where zero is putted on the middle of that. Therefore negative and positive percentage of error are defined.
Negative (positive) sign for the errors which are smaller (larger) than ideal output.

Questions:

1. Is there negative percentage of error?
2. which type of presentation (histogram, table, curve...) is sufficient and typical to show the error of a circuit?

Best regards
 

Yes, of course there is negative error percentage. Just about everything that has an error specified has it specified as +/- x%. You can present the information anyway you like, I don't there's any 'best' way of displaying it.
