Transient Difference Plots unable to refresh

Harloeworld

Hi,

 Currently, I encountered some problems when using IC 6.1.3, specifically the calculator functions - Logic Operations. After the first run of simulation, it seems as if memory registers used in Logic Operations such as subtraction (essential for differential signals) were logged and unable to clear and refresh itself in the subsequent runs.

Thus, from the second simulation onwards, even though individual transient signals were updated in their waveforms and data, however, both "transient difference" and calculator's waveform of "wave1 tran-tran MINUS wave2 tran-tran" results still remains the same, i.e. identical results and waveform as the first run.

Ideally, results of the logic operations should be updated, in accordance to the updated results of their component transient signals. However, this is not the case.

Hope to seek clarification on what the problem may be.. For your kindest assistance please. Thank you very much. Cheers!
