For BSIM4, with l, xl, dlc given, the model code says

if (l + xl - 2 * dlc

Already been down that path. None of those suggestions apply. ...Jim Thompson

Don't look *that* closely at the expression, it is an inexact approximation of the C code. In words: "l + xl - 2 * dlc" should be positive, where L = channel length XL = L offset for channel length due to mask/etch effect DLC = Delta L for C-V model (Those three are model parameters of the B4SIM family.)

There are some more "civilized" strongly-typed languages that only allow you to true/false test boolean types, so you can't just say take 0 and and 137 to it and have it evaluate to "true." Like Java. Blech.

John,

1. In most languages (including BASIC, C and so on), arithmetic operators take precedence over conditional operators. The statement is unambiguous.

You claim to know C, and write in BASIC, so you /must/ be aware of this.

1. Even in a language without OoO, the result is not ambiguous, just different: (((W + xW - 2) * DWC)
