FFGEN - Problem with synthesizing FabScalar with Nangate library

[emsey]

Hello there,

I am trying to synthesize FabScalar with Nangate 45 nm cell libarary.
When I synthesize it, I get this warning:

Warning: Target library contains no replacement for register 'lsuPacket0_reg[62]' (**FFGEN**). (TRANS-4)

And when I look up into the generated netlist I have something like this:

\**FFGEN**  lsu_lsuPacket0_reg_62_ ( .next_state(1'b0), .clocked_on(1'b0), 
        .force_00(1'b0), .force_01(n171085), .force_10(1'b0), .force_11(1'b0), 
        .QN(n149787) );

I have all the flip flops "set_dont_use" commented according to this: https://www.edaboard.com/threads/170129/
As I read here and there, it seems like there is a problem with set reset of flip-flops in the cell library. Any help with changing the cell or other solutions?

Thanks
