AMS Simulator in cadence virtuoso

Pandurangaiah

I am using cadence IC 6.1 version.

 I am using verilog ams and created test bench in schematic,to simulate a cell i have created a config view for test bench.I came to know that we need to create a config file if verilog ams code and ams simulator is used.I could do transient analysis for config view using ams simulator, but may i know how to plot resistance on y-axis versus voltage on x-axis curve using ams simulator in cadence (i.e. how to do DC simulation plot for config view) .I have saved DC operating point,and seen results in results->print->Dc operating point.

The problem is as config file has no option of sweeping a variable while dc analysis, how to choose a sweep variable, let us say voltage  or current on x-axis.

Please give the response as soon as possible as i am struggling for this since 2 weeks.

 

Thank you.

  • "IC 6.1 version" is a bit vague. IC6.1.0 was released in 2006, and so we've got 10 years of different versions, including 8 major releases in that time.

    Anyway this is nothing to do with "config file" - it's a simulator setting in ADE, not the config view. DC sweep in AMS has only been added recently - in IC617 ISR5 (6.1.7.500.5). It might be that you could do this during a transient analysis too - if you are able to plot the resistance versus time, and voltage version time, you can then use the right mouse button menu over the x-axis in the ViVA graph to change the x-axis to be (say) the voltage signal. Not sure if that does what you want, or whether you really need the dc sweep.

    BTW, this forum should not be used for urgent questions as it is manned purely by volunteers - I'm answering here sat in an airport lounge waiting to board - there's no guaranteed response. If you want that, you should contact customer support.

    Kind Regards,

    Andrew.
