Correlating Software and Analog Outputs In a CAN Controller

This is Hint 7 of the article "8 Hints for Debugging Microcontroller-based Designs", by Pascal Mestdagh, EUROCORPS, Telecommunications Division

Until recently, troubleshooting mixed-signal designs, where you need exact time coherency code, was extremely difficult. The problem could be partially solved by combining a logic analyzer and an oscilloscope with common time bases and triggering them simultaneously. However, time base differences between the two instruments could lead to incorrect results. Moreover, differences in memory made things even more difficult. An alternative is to use a hybrid scope/logic analyzer. These instruments enhance cross-domain measurement accuracy and can reduce debugging time for mixed-signal designs.
