RTL Compiler: How to locate registers with unconnected reset port

hnfq

I am currently using RTL Compiler for synthesis and have been trying to figure out a way to list all registers in the design that have unresetable registers but with no success. The design that I am working on only has synchronous reset. I am not concerned about the pipeline registers (that do not feed back into the design) but I would like to make sure that all rest of the flops do have reset port connected to sync_reset input.

Any suggestions on issue would be greatly appreciated.

    I think the best approach is to look for the know reset pin name;

    rc> find / -split -vname -pin pins_in/RST

     alternativly you can start at the root and use 

    rc> fanout -end -struc [find / -pin my_source_reset_pin]

     

    Cheers,

    Thanks Mike.

    I am going to try both the options and see if I manage to get the desired result.
