Integrating Perl with Ocean

Hello,

Please i need help with the following questions.

First i need to explain what i want to do: 

I have a Perl script which will generate a file contains variable values which will be used in the netlist to simulated. Then this netlist will be simulated using an Ocean script which will put the outputs in an output file. This output file generated by Ocean will be passed again to the Perl script to do some calculations on these values.

So my questions are:

1) Can we integrate Perl with Ocean in the mentioned sequence of operations?

if yes, then how?

If no, then what is the other way to  achieve the same goal.

2) How to pass files between perl and ocean?

3) Instead of passing the outputs from ocean again to perl to do some calulations, can we make it directly inside ocean then make the final output file of ocean contains the final needed values. I mean the normal testbench outputs are some currents, then i calculate the difference between the values before and after the layout. So can i make ocean do this calculation dierctly instead passing again to perl?

Your help is highly appreciated 

Thanks

Regards,

Inas
