Custom netlisting procedure

jmss over 13 years ago

Hi,

I am trying to customize the netlist procedure for hspice.

In the hspice view I configured these properties:

hnlHspiceFormatInst = dummy()
hnlHspiceParamList = hnlHspiceMOSfetParamList

Then I wrote dummy() like this:

procedure(dummy()
printf("Custom netlisting procedure...\n")
inst = hnlCurrentInst
print(inst->??)
formatter = nlGetFormatter(inst)
;nlPrintInstName(formatter, inst)
)

When I run netlisting with:

simInitEnvWithArgs(runDir libName cellName viewName "hspice" t)
simReNetlistAll = 't
simNetlistHier = 't
netlist()

I get this error:

Running netlist

I can't find anything on this error. Is it related to mixing nl and hnl functions?

Any help would be appreciated.

Best regards,

The nl functions are for the "direct" netlisters, as used in ADE. So that would be where the netlister is hspiceD. The hspice netlister is a traditional hnl netlister.
So you are mixing in the nl functions in an hnl netlister, and that doesn't make sense.
Regards,
Andrew.

Hi Andrew,
Thanks.
Can you show the skeleton for an hnl-based netlister?

Hi Joao,
I don't have one to hand (I don't tend to see too many questions about the hspice rather than hspiceD netlister). Best thing is to log a service request for this.
Regards,
Andrew.

Thanks, I've created an SR.
Just one more question: is that because hspice will be dropped and hspiceD is to be made the one official netlisting method?
Regards.

No, there are no plans to drop hspice in favour of hspiceD. They're just different interfaces (one from schematic, not CDF based, and the other from ADE and is CDF-based).
