ADS HDL Cosimulation

Hi,
I tried the example SDFHdlCosim, with Modelsim as vhdl cosimulator. However, I get the message that "Could not load/found the specified procedures: sdfsynthstars, Sdfhdlcosimstars, sdfstars, sdftclstars. These files (.dll, .lib) are all installed in C:\Ads2008\Adsptolemy\lib.win32/lib.win32_64. Is there an environment variable for WinXP or ADS config file which need to be set? I am using WinXP SP2 and also tried it with Filrewall disabled.
Thanks,
R

A sample message:

Simulation / Synthesis Messages
Error detected by hpeesofsim during netlist flattening.
Could not load sdfsynthstars: The specified procedure could not be
found.. Running the simulation from the command line may give a more
detailed error message. See the "Building Signal Processing Models
From the Command Line" chapter of the Ptolemy manual for instructions
on how to do this.

No one else has this question

Are you running in 64-bit mode?

Can you run a simpler example, e.g. SineGen connected to a NumericSink, or does this also fail?

Hi,
Thanks for reply. I think is 32bit. How do I select 32 or 64? Is the simpler example a vhdl cosim? Do I need to set any environmental variable like PTOLEMY_PATH_???
Thanks,
R

If you start ADS from the Start button > All Programs > Advanced Design System XYZ > Advanced Design System, then all the variables should be automatically set for you.

On 64-bit machines there is another option under Start button > All Programs > Advanced Design System XYZ for 64-bit simulations.

Anyway, if your machine is 32-bit then the 64-bit option will not be there.

Are you running ADS 2008, or some earlier version?
If you are brand new to Ptolemy, to create a simple example open a new schematic (choose the Signal Processing option), and from the palette on the left select the SineGen component and a NumericSink component. Connect them. Add a DF controller (again from the palette on the left) and press the simulate button. Does this work or does it give a similar error?

Yes, I am running ADS2008. I try it again, but other rf example (non cosimulation) I tried work ok. I followed the default installation. Also, I set the WinXp environment varaible for MTI_VCO_xxx to 32 and the same error. What kind variables should I see in registery under ADS2008-->eeenv? Is any manual varaibles need to be added to WinXP environment?

What was the "other rf example (non cosimulation)" that worked for you?

Was it a Ptolemy (Signal Processing) example?

I have never heard of the variable MTI_VCO_xxx. Is it mentioned in the documentation?

Anyway, you should not need to set any variables to get the examples to work.

You probably have to call Tech Support to assist you with this.

MTI_VCO_? is an environment variable for Model Technology Simulator which was mentioned in installation setup, I believe. I have to look it up again.

Ok. I tried the examples: RFIC\Amplifier_prj and RF_Board\PLL_Example\DECT_LO_Synth_prj, they worked. I tried a simple generator and a TkPlot and got the load/not found error as SDFHDLCosim. What does this mean?
Thanks,

Do you happen to have Active HDL (from Aldec) installed on the machine you are getting these errors?

Yes.

Aldec ships a dll (sdf.dll) with the same name as a dll that ADS ships. If the PATH environment variable has the directory where the Active HDL sdf.dll file exists (probably c:\Program Files\Aldec\Active-HDL\BIN) then the ADS dll will not load properly.

Try removing this directory from your PATH.
