AMS simulation

[dinac]

Hi all,

I have a problem here.

i imported the verilog netlist of a small FSM and the simulation works
fine.

But the problem is that , i need to feed through the analog output to
the digital input ( which i hve them in the form of netlists).This
analog output acts an Enable signal.

The use vdd=1.1, the analog output goes from .5v to 1.1v. but the
digital input does not recognises the x state, only 1 or 0. so i
included the E2L_2 module from connect_lib ( which is verilog.ams) and
trying to simulate.

To simulate this, I created a config cell view , and in the ADE, setup
--> simulator/Host to ams. and start.
should i care of any thing else, before i do the simulation.

i got the following Error.

ncelab: *F,INTERR: INTERNAL ERROR

Hi Dinac,

As suggested by the error message, you better get in touch with your
CDS customer support.
Seems that this 64-VPI shared Lib is not found.
I'm just wondering if this library does not exist for true or AMS
didn't manage to find it.

My attempt to help you meanwhile is :

1. Can you check your LD_LIBRARY_PATH env variable ? I would recommend
to fire up a unix xterm from your CIW
2. What about running AMS using the HED model ?
3. Try the 32-bit option if you want to move forward awaiting for a
final fix. You could do this by excluding AMS from the CDS_AUTO_64 env
variable.

Again, the best way is to get in touch with your CDS Support ASAP.

Cheers,
Riad.
