I've been trying to run smoke analysis on my design for a while. I've managed to run it on active devices (FETs and diodes), but it refuses to run on passive components - subcircuit based .lib files. For example I have an inductor with the following model:
.subckt ind_reg0 1 2
L1 1 3 10e-6
R1 3 2 0.3
I also added the following definition to device property file:
( SYMBOL_NAME "inductor" )
( MODEL_TYPE 2 )
When I run smoke analysis (after transient) I get the "non-fatal error: Current data not found for Smoke test LI" I've verified that I check "All" in data collection options. I also tried updating node names in pre-smoke section of template property file. But nothing helped.
Does anyone have an idea how to run smoke analysis on subcircuit based passives?
Thanks in advance for you help!
I tried using passives from analog.lib: a source and L and R. I saw that both parts have already some properties deifned as variables: for example inductor has CURRENT property with value set to LMAX. I ran smoke and somehow it already had some ratings specified for the resistor, but not for the inductor. I tried defining variables with PARAM part, but it didn't change anything.
How these variables (LMAX,DSMAX,RMAX etc) should be specified to be passed to Smoke analysis as ratings?
First, thank you for your help.
I added the Variables part. And yet it doesn't work for inductor. I could get smoke analysis for a resistor (PDM, TB and RV) and a capacitor (CV and CI), but nothing for an inductor. Also, for some reason the resistor PDM gets 0% derating all the time, and I didn't specify it.
I have also one additional question. How can I use resistors and capacitors having only symbol definition (.olb) in smoke analysis. I know that pspice somehow recognizes such parts (once the value is specified) and can simulate it. These components also have RMAX/CMAX etc attributes assigned automaticaly. But once I run the Smoke analysis, it skips these parts.
