Multisim NI ELVIS II Schematic Simulation Generates False Triggers and/or Data DiscontinuitiesPrimary Software: Electronics Workbench>>MultisimPrimary Software Version: 10.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I am using Multisim with NI ELVIS II, and I am acquiring data using the Scope. I have seen cases where my trigger is activated on the wrong edge (rising or falling). I have also seen discontinuities in my input data. Why does this happen, and how can I avoid this issue? Solution: In the NI ELVIS II Schematic in Multisim, the DSA and the Scope instruments share the same pins. When these two instruments are enabled at the same time, the data acquired during the simulation can be corrupted. This corruption can look like triggering on the wrong edge and/or discontinuities in data acquired on CH0 and CH1. The work around for this issue is by disabling the instrument not currently in use i.e. either the Scope or the DSA when running a simulation. In order to disable an instrument, right click on the instrument and select NI ELVIS II Instrument Enabled in Simulation shown in the Figure 1.  Figure 1: Disabling Scope Instrument in NI Multisim. This issue is scheduled to be fixed in a future version of NI ELVISmx. Related Links: Knowledgebase 4X6B37C5: Common ELVIS Questions Attachments:
