VerilogA Debug

Hi,
I am new to verilogA and am trying to debug a simple block using
hdldebug tool. Once I give the Debug Netlist File from the main menu,
the simulator does start, but then it gives errors like -

Notice from spectre during circuit read-in.
"/home/student/vineet/AMS/Thesis/ad_conv/veriloga/veriloga.va" 3:
Illegal
character ``' in input ignored.
Error found by spectre during circuit read-in.
"/home/student/vineet/AMS/Thesis/ad_conv/veriloga/veriloga.va" 3:
Syntax
error in specification of `include'.

The statement that its refering to is

`include "discipline.h"
`include "constants.h"

As far as I know this is the syntax for include statment...if I am
wrong about that please correct me !

regards,
Vineet.

 

Vineet:
Are you using the tick mark that is slanting left (under the ~ in
upper left hand corner of keyboard) and not a single quote in the
`include?

If you are using IC50 I think the extension on the discipline and
constants files is .vams instead of .h.

 

Hi Erik,

No, that was the 1st thing I chked. I am using the correct tick ( the
one below ~ ). Infact its a code generated by Cds ModelWriter, so I
dont see how it could be wrong !! Besides, this is not the only error
that I am getting. The log is real big, and it seems to find error
with every statement in the code.

regards,
Vineet.

 

Vineet:
Does the code simulate but the hdldebugger doesn't seem to work?

Are you starting the debugger from artist or are you running from the
command line? I am thinking that if you are running the debugger
command line it can't find the discipline.h and constants.h files for
some reason.

 

Hi Erik,
I am starting it from unix prompt in the directory where I have the
file. Yes, I get what you are saying about not finding the header
files. Coz I dont see any files like ams.env that is used in AMS
Environment which has specific reference to the header files -

amsDirect.vlog includeFiles string
"(disciplines.vams)(constants.vams)".

So am I supposed to put something similar for verilog-a ? I see an
INCA_lib directory with some .pak files. But they dont seem to be env
files.

regards,
Vineet.

 

Vineet:
An environment variable by the name of CDS_VLOGA_INCLUDE can be used
to point to veriloga include files. You might try this or run the
veriloga debugger from analog artist. Or use the AMS Designer
debugger if you have access to that.

 

Hi Erik

Ya, thats what I am doing now. I have access to the Cadence AMS
Environment and the related tool set. I hit a bottleneck again ! I
have posted the question in the group regarding that ( Sub - spectre
model files). Can you please throw some light on that.

Thanks,
Vineet.
