Fixed-Point Blockset

Using External Mode or rsim Target

If you are using the Real-Time Workshop external mode or rapid simulation (rsim) target, there are situations where you may get unexpected errors when tuning block parameters.

These errors can arise when you use blocks that support constant scaling for best precision and you use the Best precision scaling option. To avoid these errors, you should use the Use specified scaling parameter value. Refer to Example: Constant Scaling for Best Precision for a description of the constant scaling feature. Refer to Block Reference for a description of blocks that support this feature.

For more information about external mode or rapid simulation target, refer to the Real-Time Workshop documentation.
