.STEP nested command not working

[snafflekid]

I am trying to sweep the value of a parameter with the .STEP command (I am using ELDO if that matters)

What I want to do is go through a list of parameters like this:
.STEP PARAM VSS VDD LIST (0 3) (0 5) (-5 5) (-8 8)

and then use the values set in VSS and VDD to sweep another parameter:
.STEP PARAM S VSS VDD INCR 0.1


but I get an error saying:

Error: (eldo - 1655) Unable to have a STEP boundary changed at run time. This is occurring
+ dealing with the 2nd .step command where VSS is supposed to be changed.


Is there a workaround solution?

Definitely, other SPICE variants don't even have the parameter vector syntax.

Is there a workaround solution?

No convenient one, I fear. The error message suggests that the developers have been well aware of the restriction.

I think you could use the .ALTER command to redefine VSS & VDD
