* OSDI codegen self-test -- PDK-free, generic made-up coefficients.
*
* A voltage-dependent resistor and a voltage-dependent capacitor, written as
* behavioral value expressions. The parse-time OSDI transform must compile them
* into native compiled-C OSDI devices (log shows "-> N C-OSDI model(s)"), and
* the analyses must run to completion. Contains NO foundry data.
*
* Expected: op current i(vr) = -V / [r0*(1+k*V^2)] = -1/(1000*1.1) = -9.0909e-4 A.
