1. go through .cdl file and find the pin order in the subckt and put that info into associative arrays with cell names as keywords.
2. Parse the verilog netlist ,and find a cell name and pin names,and net names connected to each pins.
3. Put the cell name into the associative array from #1, and associate the pin order in subckt with net names from #2.
4. Add 'X' to the instance name and print it as well as net connetion info and cell name from #3.
5. Go to #2.

it's not very hard if the netlist is flat.

Got it...appreciate your help.

@lostinxlation and @Pavan,

I am still confused. I am stuck at this point since a few weeks and want to move ahead. I have verilog file and I need TRANSISTOR level spice netlist. how do I get it? I do not know Perl.
