When my customers want that, I'll go that way. I might look into it,  
and nudge them a little. You have me interested. But on my last (and  
first) IC design, the deliverable in the contract was a SPICE netlist.

In any case, can't these new formats handle hierarchy? I would think  
it preferable to let the simulator do the expansion, not the  
netlister. Am I missing something?
