I am not able to simulate a Vsin source from the analogLib library in a transient simulation. I get the error message, to specify the waveform type of the source!!! Any help would be greatly appreciated!! I have attached the screen shot below.
 

it's hard to tell from the pic you attached. you have to check your vsin parameters. for transient analysis, make sure you have two voltage levels i.e. 0v and 5V, rise time, fall time, duty cycle, source type (sine, rect etc.). Nothing wrong with your ckt. there's hardly any ckt where things can go wrong. Most likely, your vsin settins.
 

Vsin as it says is a sinusoidal symbol so there is no place to specify rise fall time or the duty cycle stuff, its should just be a sinusoidal wave, given the amplitude and frequency which I have specified.
I think this is a cadence configuration problem. I am working on it.
 

Change your environment setting as...


CDS_Netlisting_Mode="Analog"



Look at carefully " signs. It's a bug of Cadence.

From where can I change this setting?
Click to expand...

These environment setting are in either .bashrc or .cshrc file in home directory. Definition of Cadence environment settings are put in those files ( one of them )
 

i have the same prob but it doesn't work with me although i changed the environment variable
CDS_Netlisting_Mode="Analog"
and i changed using bashrc and cshrc
the same error appears
plzzzzz help
 

I have the same problem... I've already changed the environment variable CDS_Net_Listing_Mode to Analog
could someone help?
 

You should not use "Analog", it should be Analog. It works.

Thanks Bigboss!!!!!!!! You solved a great problem!!

Only one thing I would like to mention is that,
the line you mentioned is for the ".bashrc" file. Whenever setting for a ".cshrc" file, the command will be:

"setenv CDS_Netlisting_Mode Analog"


Cheers!:):)

bzaki,

change the command for ".cshrc" file from
"CDS_Netlisting_Mode="Analog""
to
setenv CDS_Netlisting_Mode Analog
