Why does my model recompile during estimation when running in Accelerator mode?

I select the Accelerator mode before running my model. This should cause my model to compile only once during iterative estimation. However, my model compiles repeatedly during estimation.

This enhancement has been incorporated in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:
Some Simulink blocks require the model to be compiled again when their parameters change. For example, if your model contains the "Fcn" block with an estimated parameter, the model must be compiled each time the parameter value is updated by Simulink Parameter Estimation. If possible, you can replace such blocks in your model with a combination of more basic blocks that perform the equivalent operation.
