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

Paulux

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

  • From Cadence Analog Design Environment User Guide (Product Version 5.0) p.135 (About Subcircuits and Macros), it mentioned

    "Whenever possible during hierarchical netlisting, subcircuit names are generated in the form _libName_cktName_schematic

    For example: .SUBCKT _mylib_bicomp_schematic n0 n1 hsbias out

    This name generation is not possible when a subcircuit is parameterized (that is, when it has parameter values passed in through macroArguments in the stopping cellview CDF). In this situation, subcircuits are named subX, where X is a unique number. For example:

    .SUBCKT sub3 D G S

    If you want to have nonparameterized subcircuits named in the subX style, add a dummy parameter to the macroArgument field of the CDF for the stopping cellview."

    My questions are 

    (1)Based on the above description, may I know how to change the instance name from  unmos4_schematic to unmos4?

    Or is this impossible? Or any other method that I can stop generating "_schematic" after the instance name unmos4?

    (2)Where can I set stopping cellview CDF?

    Thank you very much for your feedback/comments
