Abstract:
A method for margining error rate of a multi-drop data bus comprising the steps of:determining a lowest acceptable level of a predetermined parameter at a highest nominal data transmission rate across the data bus, determining a highest acceptable level of the predetermined parameter at said transmission rate across the data bus, determining whether a difference between the determined lowest acceptable level and highest acceptable level is greater than a predetermined minimum error margin, and if so, setting the predetermined parameter to a nominal level lying between the determined lowest acceptable level and highest acceptable level at said first data transmission rate, and if not, repeating the steps of determining the lowest and highest acceptable levels at progressively reduced data transmission rate until the difference is determined to be greater than the predetermined minimum error margin, and setting the predetermined parameter to a nominal level lying between the determined lowest acceptable level and highest acceptable level at the reduced transmission rate.
