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.

  • To answer (rather belatedly) your original question about saving the internal variables, bring up the test editor (double click on the test name in ADE XL) and then Outputs->Save All and set the "Save AHDL variables" to "all". You can do it more selectively, but you either need to add a probe tcl command or do this from within the SimVision debugger - so it keep it simple, you can get all of the internal variables this way.

    After simulation, you can use the results browser to access the internal signals.

    I've no idea what your last two questions are trying to ask. If you were (via some roundabout way) asking about using Setup->Stimuli when using AMS as the simulator - the simple answer is that it doesn't exist. This is only there for spectre.
