[myhdl-list] ListElementNotUnique error

[Jens P. A. <je...@if...>]

Hi, I hope someone who knows more MyHDL/Python than myself can have a look  
at this:

I keep getting the following error from toVerilog():
List contains Signals that are not unique to it

I have a list of signals. The signals are driven inside a module, called  
like this:

     signal_list = [Signal(intbv(0)[WIDTH:]) for i in range(NUMBER)]
     insts = [module_name(signal_list[i]) for i in range(NUMBER)]

I want to compare the outputs from all the instances, to select the  
highest one. So after the previous code, I add the following:

    @always(clk.negedge)
     def select_best():
         """Compare values and select the best one"""
         best=0
         for nr in range(NR_REGS):
             if signal_list[nr] > signal_list[best]: # I have also tried  
.val on them
                 best=nr

	max.next = best

This gives me the ListElementNotUnique error from the toVerilog converter.

Is it not supposed to be possible? How should it be done?


Thanks,

Jens Petter Abrahamsen.
