Netlisting error when using hspiceD simulator in cadence 5.14

isazulkc

 Hi,

I want to use hspiceD simulator to run some basics noise analysis on a single NMOS M1, but the netlist and simulation fail.

 the switch view list in  the simulator is : hspiceD spice cmos_sch cmos.sch schematic

 the stop view list  in the simulator is:hspiceD spice. And I created a hspiceD view of the nfet by copy+paste+rename the symbol view.

  I get this error:

**** "Begin incrementl netlisting

Netlist Error: cannot find any info on instance "M1" in cell  "LibraryName" "Cellname" "Schematic" 

End netlisting

ERROR (OSSHNL): Error(s) found during netlisting. the netlist  may be corrupt or may not be produced at all"

 

I tried many thing but no one works:

 ***** When I add symbol view at the beginning of the switch list I got this error:

WARNING: Netlister: The switch view symbol of cell nfet in library cmosp18 has no instance, hence is being ignored.

To netlist this cell, add this view to the stop list and to ignore any particular instance use nlAction="ignore"

The same message is for the cell Vdc from analogLib.

 Then when I add symbol view to the stop list, I got the same error as the first presented.

 

How can I fix this problem and run a simulation with hspiceD in Cadence 5.14?? any help will be very very appreciated. I don't what to try anymore.

 Thx!

  • If you do Tools->CDF->Edit CDF, and pick the nfet component, is there anything set up in the hspiceD simulation information? My guess is that nothing is defined in this part of the CDF and as a result the netlister does not know how to netlist this component.

    Adding symbol to the beginning of the switch list makes no sense, because it will then try to traverse hierarchy in the symbol views (assuming it is not in the stop list) and there won't be any, hence the error. If you were to add it ("symbol") to the stop list too, it would never traverse any hierarchy. Not really sure why you tried doing this, because it doesn't make any sense.

    Anyway, the most likely cause is the lack of hspiceD CDF simInfo.
