How to override netlisting mapping of instance names and node names?

Hi,

I'm using IC6.1.5 and an external simulator.  It has a predefined set of mapping functions that convert schematic names to netlist names.  For example, if I name a node in my schematic to begin with a "." (like .monitor for example), this name get converted to _net0 during netlisting.

I want to override this default behavior so that I can control the mapping, but my attempts so far have been unsuccessful.

Here's what I did:

I defined the $SIMRC to point to a directory in which I have my own .simrc file.  In my .simrc file, I defined

hnlSetDef('mapNetFirstChar
    list('("." "net_")
    )
)

After this, I have completely exited IC and restarted.  I reopen my saved state for the external simulator and from the ADE menu I do a Simulation > Netlist > Recreate.  However, my netlist still contains _net0 instead of the desired net_monitor for the net named .monitor in my schematic.

What am I missing?  Do I need to force unbinding somehow since mapNetFirstChar has been previously defined by the external simulator?  How do I do the unbinding?

Thanks in advance for all tips and help.

    SharksFan,

    The variable you're using will get set by the "nl" layer - this is the "direct" netlisting system used in ADE which provides an object oriented approach to defining netlist formatters. The way that some of the netlisters handle the ability to customize some of the mapping is by then supporting a netlister-specific variable which is then used to pass a setting to nlSetOption within nlInitialize. For example one such variable for the spectre netlister is
    hnlSpectreMapNetInName (there are solutions describing this)

    Maybe the interface you're using has something similar.
