ERROR (SFE-23) when run sprctre with DSPF

huqy

when I run spectre with DSPF which created by calibre, it hints me ERRORs like below.

 ERROR (SFE-23): The instance `XXinst_rect_power_stage_1/Xinst_hs_pwr_stg/XIhsdrv0/XI3/XI3/XI7/RR0' is referencing an undefined model or subcircuit, `200'. Either include the file containing the definition of `200', or define `200' before running the simulation.

the “undefined model or subcircuit `200'”  is the value of the resistor.   

the it's corresponding CDL  is below

RR0 vdd net7 200 m=1 $.MODEL=PR

and the DSPF  describe like below

XXinst_rect_power_stage_2/Xinst_hs_pwr_stg/XIhsdrv0/XI3/XI3/XI7/RR0:neg rppo1rpo 200 w=1.5e-06 l=1.05e-05

when I delete “200”  manually，it works fine. I do not need this parameter.

so, is there any way to ignore this error.

 Thanks

  • I was going to ask whether you were including the DSPF via the dspf include on Setup->Simulation Files, or as a DSPF view, but to be honest the file just looks wrong to me. If that's the full statement, then there's no connections to the subckt instance, and I'd expect the resistance to be passed by r=200 rather than just as a value (it's different in the CDL, because CDL is a SPICE-like language and uses the R in the instance name to indicate that it's a two terminal resistor, and hence the 200 is the value. With a generic subckt, it doesn't know how many pins to expect.

    Of course, you may not have shown the entire subckt instance, but I think you need to investigate what is wrong with the Calibre DSPF generation (which is better to ask Mentor about, since it's their tool).

    Regards,

    Andrew.

    hi andrew,

     the dspf is included on Setup->Simulation Files.

    I found a rule that the build in device Resistor (R0 - R9) will extract R value. others only extract with name w ,l.  the all instance section in DSPF as below,

    As I mentioned in my previous reply, Calibre is a Mentor (not Cadence) product, and since I don't have access to it, I can't offer you support on it. For questions about how to control Calibre to affect the writing of DSPF generated by that tool, you should contact Mentor support or their own forums (I think they have them too).
