using trise(dtemp) in an instance

[Riad KACED]

Hi,

Of course the trise is supported in Spectre.
I've created a little testbench: 2 diodes forward biased with a VDC
source @ 2V:
//
D1 (net1 0) myPdiode l=W w=W m=1
D0 (net1 0) myPdiode l=W w=W m=1 trise=TRISE
//
trise is an instance parameter.

I include the model file where ''myPdiode " is defined :
include "MyPath/myPdiode.scs"

I run a DC sweep on TRISE from -50C up to 100.
The result is here attached:

My myPdiode.scs model file is a model you can find in the VirtuosoŽ
Simulator Circuit Components
and Device Models Manual.

More details about your netlist would be helpful.
Please don't post any proprietary data (models cards, files ...)

hi Riad,

Thanks a lot...

Actually i did try this, but the problem was that I was not using the
diode in a right way that it is used to be used( i am new to diode
simulations) , i was trying it in the reverse-biased, without inputing
the correct value.

I using these diode as a temperature sensor with a reference diode
and inputing it to a slow-adc that i hve designed. i had already fired
few doubts on the slow-adc and your answers did help me out as these
did.

thanks again....
