Eldo netlist generation with ADE L.

sypetre

Hello,

I try to generate an Eldo netlist from ADE L. I configure the simulator to EldoD, but i got this error:

ERROR (OSSHNL-116): Unable to descend into any of the views defined in the view list, 'eldoD schematic verilogAe AFE_Gas_Sensor', for the
instance 'M0' in cell 'simple_test'. Add one of these views to the cell 'P_LV_18_MM' in the
library 'UMC_18_CMOS', or modify the view list so that it contains an existing view.

I saw another post talking about the same topic, but I am not able to correct my problem.

I guess writing the good parameters in Switch View List and Stop View List could help. But I do not catch how to know the right parameters to write into these boxes ? Is it technology depend ?

Hope you could help me.

Have a nice day,

Sylvain.

    My guess is that the PDK  you're using doesn't support Eldo (Eldo is not a Cadence tool - it's from Mentor (as Siemens company)). You should look (in the  library manager) for the component P_LV_18_MM in the library UMC_18_CMOS and check if it has any eldoD views - I assume not, because it wouldn't have failed otherwise. If it doesn't have the stopping views, it's unlikely to have the CDF setup for eldoD either, so picking another view name won't help.

    Perhaps you could simulate with Spectre instead? If you really want Eldo support you'd need to contact the foundry to see if they support a version of the PDK that supports Eldo.

    Regards,

    Andrew.

    Thanks for the answer Andrew.

    Indeed, there is no EldoD view.

    In fact, I have models for Eldo, Hspice and spectre in my PDK folders. So, do I need to create the Eldo view in cadence by my own ?

    Best regards,

    Sylvain.

    Sylvain,

    That's not a trivial job - you'd need to ensure all the information needed to correctly netlist each component is set up in the CDF - the parameter mapping, the terminal orders, etc. The stopping view itself is the trivial part (that's normally just a copy of the symbol) - it's defining the CDF properly so that each component netlists correctly for that simulator and models is a little more work. If the foundry have provided Eldo models, it's a little strange that they haven't provided the PDK setup to support it. It may be they have a flow to enable this though - hence my suggestion to contact whoever you got the PDK from.

    Andrew.
