Super ContributorHi,
between the output of the LUT (combout) and the input of the FLOP (datain) there is a switch.
Can this switch not be switched to exclude the LUT?as far as I understand, the datapath you are referring to has a specific dedication for SLOAD function. There's an optional register chain datapath, but I don't know if it's available in the present situation.
Basically fitter is selecting the best available datapath automatically, particularly considering timing constraints. Why do you worry about fitter results?
Occasional ContributorI don't need to achieve better results.
I just wanted to understand if there are any constraints or attributes to pass to the
synthesizer to connect the registers as desired.
Let's just say it's for educational purposes only
