RTL Compiler: how to get all input ports except clock ports?

airland

Dear all, I want to add input delay for all input ports (except clock ports), how I can get the list of "all input ports except clock ports"? I know how to get all input ports ([all_inputs]) and how to get all clock ports. But I don't know how to exclude clock ports from all input ports. I think it is wrong to add input delay to clock ports, is that right? As the number of input ports is so many (thousands), I don't like to write them one by one.

I used DC before and I used the following sentence to do this. This is not recognized by RC.

set_input_delay -max  2.0  -clock CLK_E   -add_delay [get_ports -filter "dir == in && is_clock == false" *]

Thanks very much!

  •  I think you are looking for

     

    rc:/> dc::all_inputs -help
      all_inputs: returns all the input ports.

    Usage: all_inputs [-clock <clock>+] [-edge_triggered] [-level_sensitive] [-no_clocks]

        [-clock <clock>+]:
            returns all input ports with input delay relative to this clock(s)
        [-edge_triggered]:
            returns all input ports with non level sensitive input delay
        [-level_sensitive]:
            returns all input ports with level sensitive input delay
        [-no_clocks]:
            returns all input ports which do not have a clock definition on them

    If you put this in your SDC file, you will not need the dc::
