How to take care of retiming during LEC if retiming is done during synthesis?
 

This is an old post not sure if this resolved. But LEC has analyze retiming -pipeline commands which can be added in the script to handle retiming scenario's.
Also if your using RC for synthesis the basic commands are exported in the dofile automatically.
 

What will this retiming -pipeline do to take care of retiming during LEC?

Regards
 

I am not sure of the algo that would run inside. But what i have seen is that when i have retiming in thenetlist i see aborts as LEC would push all logic to the PO which cause a huge combo loop.

When we use this switch it analyzes the design for retiming and does appropriate changes in the revised logic to be compared.
Youc an try this without and with and you will see the change in the schematic.
