Why spectre generated-netlist always show the wrong subckt name "unmos4_schematic" but not "unmos4" ?

Hello,

I want to build a cell called unmos4 and hope the spectre-generated netlist showing as follows

.subckt unmos4 D G S B

parameters nw=1 nl=1

M1(D G S B) ne2 w=nw l=nl as=0.49*(nw) ad=0.49*(nw) pd=0.98+2*(nw) ps=0.98+2*(nw)

ends unmos4

MN0 (out net043 gnd gnd) unmos4 nw=3 nl=0.35

HOWEVER, the result shows that there is extra "_schematic" after unmos4

.subckt unmos4_schematic D G S B

parameters nw=1 nl=1

M1(D G S B) ne2 w=nw l=nl as=0.49*(nw) ad=0.49*(nw) pd=0.98+2*(nw) ps=0.98+2*(nw)

ends unmos4_schematic

MN0 (out net043 gnd gnd) unmos4_schematic nw=3 nl=0.35

 

May I know how to remove "_schematic" after unmos4?

 

The CDF is as follows

Component Parameters

model paramType=string, parseANumber=no, parseAsCEL=yes, storeDefault=no, name=model, prompt=unmos4

Simulation Information

Choose Simulator=spectre, otherParameters=model, instParameters= nw nl, componentName=unmos4, termOrder=d g s b

Same problem of extra "_schematic"  is also found when hspiceD netlisting for simulation.

 Choose Simulator=hspiceD, instParameters= nw nl, componentName=unmos4, namePrefix=X, termOrder=D G S B, termMapping= nil D \,D G\, G S \,S B \,B 

Thank you very much in advance for any help, feedback and comments

     The macroArguments stuff is primarily for stopping views - it's if you want to reference an external subckt model - and it's for hspice - not spectre. Even then I think it's for hspiceS, not hspiceD.

    I believe that the _viewName will only get added if you have used a config and more than one view has been selected - In general it should just use the cellName as the subckt name.

    I'm not sure why it necessarily matters, if everything is consistent - but maybe the best thing is to provide your data (to customer support if you can't provide it here) so that somebody can take a look?

    Regards,

    Andrew.
