Importing spectre netlist with arrayed net names

Hi Steven,

You'd need to modify your netlist so as to have the A terminals placed in a bus that match the CDF termOrder:

I0 (VDD VSS A<2:0>) myInstance

I myself use a script to do this (when extracting a layout to a .dspf spice-equivalent netlist, before I spice-it-in to get the extracted schematic).
This script also proceeds to the '< >' and '( )' to=> '[ ]' changes wherever necessary in the spice netlist (usually where there's ':' or '#' right after the '>').

I mention this because one might get the same "Expected:5 Found:3" error in case a line in the netlist is in the form:
Xinst(1):Instance pin1 pin2 pin3 InstanceName
The '()' brackets act like a separator and Spice-In would consider '1' and ':Instance' as 2 extra terminals. Whereas the following causes no problem:
Xinst[1]:Instance pin1 pin2 pin3 InstanceName

This reply (to a fairly old post) doesn't make much sense to me - you can't put (unexpanded) buses in a spectre netlist - so the example you give doesn't make sense (and is not legal syntax).

If you want to use DSPF, you can do so nowadays using the dspf_include construct - which is available through Setup->Simulation Files in ADE. This can allow spectre to be able to map between the bus delimiters used on the schematic side and those used in the DSPF - and you also don't need to worry about pin ordering either.

Thanks Andrew for the insightful comment... still much to learn.
I've replied to this old post because I was looking for some help on the topic not so long ago... finally I could find it myself, so I wished to share.
I should have precised, I've used this step on an ASSURA QRC extracted .dspf netlist, which I wished to transform to an extracted schematic view using the Spice-In tool (File>Import>Spice...).

Nevermind. I guess your way is more straight-forward, still I like having an extracted schematic view on which I can add or remove parasitics or replace circuits bits (eg. sizing MOS vs parasitics, etc...)

True, I could also do this in the .dspf directly (well actually I do since I also have a procedure to disconnect parasitics on specified nets -commenting them out in the dspf- prior to the Spice-in) but could be risky in my view if you loose the overview.

As for the buses, the Spice-in of a .dspf netlist doesn't work for me if I don't put pins into buses... what my script does is simply copying the termOrder in place of the extracted dspf .SUBCKT declaration at the beginning: 

    l_TermOrder = cdfGetCellCDF(ddGetObj(myLib myCell))->simInfo->spectre->termOrder
   TermOrder = ""
    foreach(w l_TermOrder TermOrder = strcat(TermOrder " " w))

    i = infile(myDspfNetlist) 

    while(gets(l i)
        if(pcreMatchp("^.SUBCKT " l) then ;# detected the .SUBCKT line
          fprintf(o strcat(".SUBCKT " cadr(parseString(l)) " " TermOrder "\n"))
   ;#... etc
