save currents in a spectre netlist, run the netlist in batch mode and the currents is saved as instance_name:number

ckseok

To save current into port "A" of instance "IDRIVER", I add the following line in the spectre netlist.

save IDRIVER:A

Then, I run the netlist in batch mode.

After simulation is finished, the result browser shows IDRIVER:2 instead of IDRIVER:A.

How can I make the simulator save current as Instance_name:port_name instead of instance_name:number?

Thank you.

     Andrew,
       Thanks for your reply.  Looking into this a bit further, the goal for a particular circuit was to set a cellview type (i.e. schematic_extract, or even symbol) as a stop view in the heiarchy editor (so that the subcircuit definition is not defined in the netlist), include the model file for that cell at the beginning of the netlist (in the model files section of ADE), and then save the pin currents on the symbol in the test bench schematic.

    However, I noticed that if the cellview type IS NOT listed as a stop view, the SAVE statement will appear such as:
     ->     save I0.I0:2
    whereas if the cellview type IS listed as a stop view, the SAVE statment appears such as:
     ->     save I0.I0vplus
    where it appears as a netlist error, since there is no colon between the instance and the pin name anymore.  Is this a bug?  Do I have to fix something in the CDF parameters for the cell to prevent this?

    So, useterms=name works when the cellview IS NOT listed as a stop view, but how can I save these currents when defining the cellview type as a stop view instead?   Thoroughly confused,
    - Paul.
