SigmaStudio+ Indirect Parameter Accees Table
In old SigmaStudio you could add a parameter to the IPAT with a simple mouse right-click. Is there a similar feature in SigmaStudio+? I can only add it via the IPAT table but it gets annoying when the

[Bug Report] SigmaStudio / Eval ADAU1787Z incorrect parameter names; Real Time Parameter read values and addresses
See the attached project file. I used the Sigma NLMS block to system identify a known, 45 tap (only the first 40 taps are non-zero) FIR so I can see where the coefficients end up in the registers. See
