Hello MDL users,

I encountered another strange error running MDL
Here's the error message:

Error found by spectre in `nmoscap', during circuit read-in.
   "/home/tsmc/cadappl/iclibs/CLN65LP_1p9m/1.1a/tsmcN65lo/../models/CLN65LP_2d5_lk_
v1d1.scs" 43424: Function `ln' is undefined or is used
       recursively.

spectre terminated prematurely due to fatal error.
Job ended with error status: 2

So, I went and check in the model file section -

cg (ng nds) bsource q=(cgmin+dcg)*v(ng,nds)+vgnorm*dcg*ln(cosh((v(ng,nds)-dvgs)/vgnorm))


Strangely, this error is not seen when I run the sim under Analog Design Environment.

Pass on your thoughts about this.

Regards,
Gau

Gau,

Andrew is correct here.  The functions defined in the netlist are not MDL related in any way, with the notable exceptions of the assert statement ( for device OP pt checking ) and any expressions that are associated with
a Spectre "print" command.  In addition, when using a spice netlist, the .measure/.probe/.print statements also use MDL.  

Other than these instances any function or expression contained in the netlist is evaluated by the spectre expression
handler and not evaluated by MDL, so this is indeed a Spectre error.

Thanks,
