Fixed-Point Blockset

Rapid Simulation Target

If a parameter change is great enough, and you are using the best precision mode for constant scaling, then you cannot use the rapid simulation target.

If you change a block parameter by a sufficient amount (approximately a factor of two), the best precision mode changes the radix point. Any change in the radix point requires the code to be rebuilt since the model checksum is changed. This means that if best precision parameters are changed over a great enough range, you cannot use the rapid simulation target and a checksum error message occurs when you initialize the rsim executable.
