Retiming inside LPM_DIV

Hello all, From my test Quartus can't move registers inside math of LPM_DIVIDE inferred automatically. There is a way to do it? Thank you

The LPM_DIVIDE IP does cater for pipelining. However, how you infer that I don't know. I suspect you'll have to use the MegaWizard.

You won't be able to insert registers 'part way' through the calculation unless you infer two LPM_DIVIDE blocks to perform the calculation required and I doubt that'll gain you anything.

Cheers,

Alex
