Title: Error running Cadence ams(spectre) using actual spectre netlist
Post by richloo on Oct 7^th, 2010, 6:35pm

1)by using "OSS-based netlister with irun"
ncelab: *N,SFEDPL: Deploying new SFE in analog engine.
Caching library 'worklib' ....... Done
psvt25 #(1) I22 ( .b(VP), .g(A), .d(ZN), .s(VP));
|
ncelab: *E,SPPBYO (./netlist.vams,17|9): Parameter assignment by order is not supported for analog primitives.

Question:
Is it due to transistor model?

2)by using "Cellview-based netlister with ncvlog,ncelab,ncsim"
Work perfectly.

Do you know what this is supposed to be doing? It looks to me that you're instantiating a pmos (standard-vt, 2.5v, from a model library) with a parameter of 1. Is that length or width, or something else entirely?

I would expect it to look more like #(.l(.25u), .w(2u))
