Hello, When I run the Fixed-Point-Advisor I get a failure at step 1.5 Create Simulation reference data. The Failure message is: Simulation run: Failed The RowNames property must be a cell array, with each element containing one nonempty character I don't know how to solve this failure. Have anybody an idea how to fix this problem?

Greetings!

I have two questions in order to understand the problem: 1. Does your simulation error out outside Fixed-Point Advisor or only when you run step 1.5? 2. Which MATLAB version are you using currently? (you can see the result of the 'version' command in MATLAB) 3. Can you share the model used or describe what elements you are using (for reproduction)? Thanks!

I do have the exact same problem. In my case the error occurs only at step 1.5 in the Fixed-Point Advisor. My Matlab version is MATLAB 9.4 (R2018a). In my Model I use the following blocks: Tappes delay, Rate Transition, Demux, Delay and some calculation blocks.

Hello,

@Christoph Meyer, Rüduger Schwendemann

would it be possible to attach a simple model that demonstrates the issue? (you can attach a .zip file with the model included)

Thank you

Hi

Finally I could solve the Problem. In my Simulation I do have a InitFcn Callback. When I simulated my system (including this callback) everything works fine. But when I run the Fixed-Point-Advisor I get an error at Point 1.5. I found out, this is because of the 'clear all;' instruction. If I comment out this line, everything works fine. I don't know why but this fixed my Problem.
