HDL Coder: 'RecipNewton for Product is not supported'

Having read in another thread on here about setting a Product block into divide mode using '*/' to define the inputs, and setting the block to operate in RecipNewton mode, I gave this a try but every time I get an error stating that 'RecipNewton for Product is not supported' whenever I do an HDL Compatability Check.

Any ideas?

You can only use RecipNewton for a reciprocal, not a divide. Set the block to have inputs '/', and follow the output with a separate multiplier.

Thanks Tim, that seems to work, although I am a little confused as this appears to be different from the advice given in this link.
