Parameters Ignored By AMS Simulator

jschmitz

In the past with Spectre, I successfully used ADE XL's "parameters" feature to create sweeps without modifying the schematic.  I am trying to accomplish the same thing, but using AMS as the simulator.  With AMS, the simulation appears to work, but the resulting waveforms for each point of the sweep are identical, as if the parameter was ignored.

I see this issue with a minimal test case where a voltage source drives a resistive divider with swept resistor ratios.  Spectre shows different output voltages while AMS does not.  I searched the documentation and can't find anywhere that states whether AMS supports this feature of ADE XL.

Should parametric sweeps work with AMS?  If so, what might be wrong with my setup?

Software Versions:
virtuoso 6.1.6-64b
spectre 12.1.1
ncsim 12.20-s023
