[myhdl-list] not supported, extra positional arguments

[Neal B. <ndb...@gm...>]

BTW, all I'm trying to do here is declare a signed number the same size as 
the one passed in.  Is there an easier way?

This is OK:
def sat_rnd (x, bits, outbits, output):
    @always_comb
    def sat_rnd_logic():
        y1 = intbv (int (x >> (bits-1)), min_signed (len (x)), max_signed 
(len (x)))
        y2 = intbv (int (y1 + 1), min_signed (len (x)), max_signed (len 
(x)))
        y3 = intbv (int (y2 >> 1), min_signed (len (x)), max_signed (len 
(x)))
        if (y3 > max_signed (outbits)):
            output.next = max_signed (outbits)
        elif (y3 < min_signed (outbits)):
            output.next = min_signed (outbits)
        else:
            output.next = y3

    return sat_rnd_logic
    
But this is not:

def sat_rnd (x, bits, outbits, output):
    @always_comb
    def sat_rnd_logic():
        y1 = intbv (int (x >> (bits-1)), *extrema_signed (len (x)))
        y2 = intbv (int (y1 + 1), *extrema_signed (len (x)))
        y3 = intbv (int (y2 >> 1), *extrema_signed (len (x)))
        if (y3 > max_signed (outbits)):
            output.next = max_signed (outbits)
        elif (y3 < min_signed (outbits)):
            output.next = min_signed (outbits)
        else:
            output.next = y3

    return sat_rnd_logic
