I have a question regarding the use of non-clock tree cells on clock tree paths.
The netlist post-synthesis that I have, contains standard muxes and gating-elements on clock paths.
During the P&R clock-tree-synthesis step, clock tree buffers are inserted but the standard muxes and gating elements are not swapped to their "clock cell" version.
I have 2 questions:
1/ Is there a way to force "RTL compiler" tool to use only clock cells on clock tree paths when synthesizing the netlist?
2/ Is there a way to force "Encounter" tool to swap the non-clock-cells on clock paths to their "clock cell" version during clock tree synthesis step? I mean is there a way to fully resynthesize the clock paths with clock tree cells?
Thanks in advance for your help.
Automatically ? Not that I am aware of...........1) RTL compiler - You manually instantiate specific clock tree cells rather than infer a mux.2) ENCOUNTER - You manually ecoChangeCell to the specific clock tree cell.Shawn
In reply to fitz:
Thanks Shawn for your feedback.
Actually I use the methodology you described in 2/. I list all the cells of the different clock-trees and then swap them automatically to their "clock-cell" version. The problem I'm facing is that lot of the cells used in these clock-trees don't have an equivalent "clock-cell". For example a MUX4:1 doesn't have a CLKMUX4:1 equivalent but only CLKMUX2:1. Which means that I have to do much tricky things than simply using ecoChangeCell. Anyway, if there is no easier way I'll have to do it manually.
Thanks again and best regards,
