mixed-signal AMS simulation error

apple419

Hi,

   I was trying to do a simple mixed-signal simulation with AMS in Cadence ADE environment (6.15).

   In the setup there are two inverters. One inverter A has schematic view and the other inverter B has Verilog view. The Config view is created.

   In the hierarchy editor form, correct views are set (A has schematic view and B has verilog view).

In ADE, the ams is selected as the simulator. The ConnRules_3V_full_fast is selected as the connect rule. The OSS-based netlister with irun is slected.

   When I started a transient simulation, the simulation log shows the following error and the simulation stopped.

   irun: *E,BDOPT: Unknown option -rnm_partinfo

   Anyone have any idea what this error is about?  Is there anything I missed in the setup?

 

Thank you for the help!

Regards

  • That's odd. Your setup looks normal - the above tells me that you've not pointed it to an erroneous feature file (you should not set $AMS_FEATURE_FILE except if told to by Cadence for some reason), and it wasn't something wrong with the feature file (that's the amssim.dat) in the specific subversion you're using.

    I can't see how it would netlist -rnm_partinfo without this though. Having netlisted in ADE, can you enter this in the CIW?:

    _amsOSSIrunObj->feature_ncelab_rnmpartinfo

    Anyway, the solution is probably just to switch to using INCISIV12.2 - since that version does support the -rnm_partinfo option on irun.

    Kind Regards,

    Andrew.
