The AMS Simulator Smoke Analysis has been enhanced in the SPB16.2 release to support a few new devices. Also, the Model Editor now supports the addition of smoke parameters to devices like LEDs, Zener Diodes, Varistors, etc.
The following new devices are now supported by Smoke Analysis:
In addition, smoke parameters can be added to the following new devices in the Model Editor:
Smoke Analysis parameter details:CapacitorNew model params ESR, RTH, and POWER have been added to CAP devices. This corresponds to smoke checking for power loss and temperature rise of capacitors.Smoke Test Name Symbol param Name Symbol parameter Value “PDML” “ESR” & “POWER” "ESR" & "CPMAX"“TJL” “RTH” "RTH""CV" "VOLTAGE" “CMAX”"CI" "CURRENT" “CIMAX”"SLP" "SLOPE" “CSMAX”"TBRK" "KNEE" “CBMAX”"TMAX" "MAX_TEMP" “CTMAX”In addition two more params CVN (Max -ve voltage) & CVP (Max +ve voltage) have been added to the electrolytic capacitor analog\C_elect.
ResistorNew model param RV (maximum voltage) has been added to RES devices. This is a smoke check for the voltage rating of resistors.
InductorNew model param CURRENT (maximum DC current) has been added to IND devices. This is a smoke check for saturation of inductors due to DC current.
Voltage SwitchNew model params CURRENT, VOLTAGE, and POWER have been added to the Voltage Switch. This corresponds to smoke checking for max current through contact, max voltage difference between nodes NODE_SW_1 & NODE_SW_2, and power deration of the switch respectively.Smoke Test Name Symbol param Name Symbol parameter Value "SV" "VOLTAGE" “?”"SI" "CURRENT" “?”"PDSW" "POWER" "?"Symbol parameter values need to be added on symbol in schematic
TransformerNew model params have been added to transformer (single winding):Smoke Test Name Symbol param Name Symbol parameter Value "Primary_Current" "P_CURRENT" “?”"Secondary_Current" "S_CURRENT" “?”"Isolation_Voltage" "ISOLATION" “?”Symbol parameter values need to be added on symbol in schematic
Addition of Smoke Parameters in Model Editor:In order to add smoke parameters to a device from the Model Editor, go to Model> Add Smoke and chose the appropriate device type.
As always, I welcome your feedback!

I spoke with one of our AMS Simulator expert CS AEs and here is the feedback:
We do not provide smoke test variables for LPMAX and CVP parameters and you'll need to manually enter the values.
CVP is (Max +ve voltage) value for POSITIVE_Voltage of electrolytic capacitor present at analog\C_elect
LPMAX is maximum power value for POWER parameter of inductor present at analog\L_t
I am using 16.5 version but still i am not finding other smoke parameter you mentioned above for example CVP, also some other parameter you did not mention like LPMAX
