"Add" Features Does Not Simulate in Sigma Studio

Hi Everyone,


I'm using the Stimulus and Probe blocks in simulating the behavior of the ADAU1772.  All works fine until I try and split part of the signal with the T Connection 1772 and then after some filters, sum the 2 signals with the Add block.  Then, no matter what I do with the filter parameters, the probe plot stays the same.  I have tested a schematic with the T Connection and no Add block (just sent each signal to a different output) and the plot changes with a change in filter specification.  So it appears to be the Add block causing the problem.  Unfortunately I need to simulate the overall filter behavior with multiple signals added together.  How do I get the Add block to work with the Stimulus and Probe?


Kind regards
