WebFeb 23, 2024 · Hello, I'm using the "To Workspace" block in my design and I want it to preserve the type of the signal its logging. I am in the process of converting the design to fixed-point in preparation for HDL Coder. I've checked the "Log fixed-point data as a fi object" box in the module's mask. However, "To Workspace" will only log as double.
