User defined resistor model in Cadence Spectre
Feb 10th, 2015, 9:20am
 
Hello,

I am trying to run the simple example as depicted in the image below. But, I am not able to implement the resistor (with some user defined parameters rsh and kf) as required here!   Sad

For that, I tried to take a "res" from analogLib, and then change its "model name" to say "flickres_jdp" and also made a model file (say flickres_jdp.scs) - then added this model file from ADE->Setup->Model Path
The text put in this model file is:

Quote:
.model flickres_jdp resistor rsh=1K kf=10e-13


Getting following error:

Quote:
ERROR (SPECTRE-16384): Signal V(vout) = -2.45831 GV exceeds the blowup limit for the quantity `V' which is (1 GV)....
Analysis `tran' was terminated prematurely


My questions:

1. Is the above method okay, and is the format of the model file right?

2. Is there any option to include a ".model" statement in the schematic editor in cadence?

3. Is there any way to edit the netlist and then run the simulation?

These might be very trivial..but please help... Undecided

.model is not Spectre format.  Did you get any warnings at the start of the simulation?

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
