Controling the Spectre simulation from Matlab

Hi,

I would like to control the Spectre simulation from Matlab, i.e. I need to pass design variable values to desing, trigger the simulation and extract the result. As a second step, I would need to do this in optimization or parameter sweep loop.

My present idea how to do this is:

1) at first manually create a design using schematic editor and simulate it in ADE. This will create netlist in /netlist directory.

2) modify runSimulation file so that no IPC is being done from spectre

3) from matlab, parse the input.scs file and set the values of design variables

4) start runSimulation from matlab using system() call.

5) extract results using Spectre/RF matlab toolbox

... and run steps 3-5 in a loop.

I think this should work OK, however I wondered if there is any more straightforward / more elegant solution.

Any suggestions are welcome.

Thanks much,

Miro

Did you have any luck with this? I am interested to know as well.

Hi,
Yes, I implemented proposed solution and it works OK. I did this for the university, so there is a chance I can provide it to you as well, but I have to discuss with my boss. Let me know if you are interested.

Hi,
That sounds interesting. I was thinking of importing the netlists from Cadence to Matlab but I have no idea to do so. Can you help me, preferably with diagrams?
Thank you.
Regards,
Nor

Hi Nor,
What would importing netlists from Cadence into Matlab mean? A netlist is a description of the components and connectivity in a design - what would that mean in a numerical analysis tool such as Matlab?
Regards,
Andrew.

Hi Miro,
I am quite interested in your work. parse the spice netlist in Matlab is not so easy. For passive elements, it's not a paoblem.
For nmos and pmos transistors and some voltage source, how did you parse them and put them to MNA equations?
If you don't mind, may I contact with you by email?

Hello Miro, I'm Suhas shinde from Intel Germany.
It's really very interesting work. Can you please mail me the details of how you run spectre simulations and pass MATLAB variables and again take the spectre results in to MATLAB. Please email me on suhas_v_shinde@yahoo.com.
Thanks in advance.
Regards,
Suhas
