Cadence 6 waveform error vpwl vsrc

When I add vpulse or vpwl source to schematics, this message appears:

are given"

 

And another problem

When i add vpwl (name V5) signal with params like

 0s, 0 V

14us, 0 V

30us 5V

error appears

 "Netlist error: missing parametr V2 in V5"

 "Netlist error: missing parametr V1 in V5"

    That too looks like a lack of CDS_Netlisting_Mode being set.

    I've no idea what the second is. You didn't say how you set up the source. Where are you adding the "vpwl (name V5) signal". 

    Please try to take care to carefully describe the problem with all the relevant information. Debugging from the above is virtually impossible...

    Regards,

    Andrew.

    I have

    export CDS_Netlisting_Mode= "Analog"
    in my .bashrc

    Is problem in "Analog", quotation marks? 

    V5 params.

    Should be OK. Type (in the CIW in your virtuoso session):

    cdsGetNetlistMode()

    and see what it says.

    You may also need to do a Simulation->Netlist->Recreate to force it recreate the netlist.

    Please post the relevant line (or lines) from the input.scs so I can see what it has written into the netlist.

    Regards,

    Andrew.

    You could also look in the banner of the window that appears when you do Simulation->Netlist->Create and you'll see the full path to the input.scs file so you can copy the relevant lines for the source and paste them here.

    Regards,

    Andrew.

    That would explain it then.

    Are you starting a new shell before launching "virtuoso"? Or are you issuing some different command (maybe a wrapper, provided by someone else) to launch the IC tools?

    In the shell before running "virtuoso", what does "echo $CDS_Netlisting_Mode" show?

    In fact I think I might have guessed what your problem is. In your example above from what you have in your .bashrc, you posted:

    export CDS_Netlisting_Mode= "Analog"

    it should be:

    export CDS_Netlisting_Mode=Analog

    or

    export CDS_Netlisting_Mode="Analog"

    The key problem is the space after the "=" (note, this is a bash syntax issue, nothing to do with Cadence).

    Regards,

    Andrew.
