It is actually possible to get spectre to have the parameters looked up in the reverse (incorrect, in my opinion) order.
Historically certain other SPICE simulators used to have a rather counterintuitive (and bizarre, as it's nothing like any other language) parameter precedence - where global parameters overrode local parameters. I remember when this was introduced in one particular simulator around 20 years ago, and then I had to ask for a mechanism to make it the sensible way around.
Spectre defaults to the more logical local overrides global (which is the way thay any programming language would work). However, because we also support reading in other SPICE dialects, you can add:
in your netlist, and the lookup will be reversed. But remember that this applies everywhere. I strongly discourage you from doing this, because if you're using ADE, the parameter passing would be inconsistent with how ADE looks up parameters, and the danger is that you end up simulating something different from what you're manufacturing. That's clearly dangerous...
