SimInstanceNames in Parameter sweeps with AEL

Hello,

I would like to use AEL to individually access and change the following:

SimInstanceName[]

In the Parameter Sweep instance in ADS. As far as I can tell, the only way to change these is to re-type everything within Parameter Sweep which is cumbersome.

Appreciate your help,

Lou

Hi Lou,

Typically you can set:
SimInstanceName[1]="HB1"
or something to that effect. If you renamed the instance name of the Simulation controller say HB1 to myHB, then you need to do the change in the ParamSweep component too. Sometimes it can be cumbersome typing this in. But typically you just have to modify One field and it doesnt take up much time if you are setting up your Simulation.

Using AEL might be a way to do this too but I suspect it might be overkill for this sort of application.

Maybe you can explain your usage in more detail. Do you have lots of Paramsweep components?? And do you have to change the SimInstanceName for all of them??
Then maybe you should make this into a VARIABLE instead of typing it in.

Or maybe you have a different usage totally. Please respond on this forum with the coomplete design flow on how you are using this feature today and why using AEL might benefit you.

I may be able to help you with that information.

If it is too complicated to explain here, you are also welcome to contact your local EESOF support office.

Thanks

Thanks Nilesh for your quick reply,

I am using AEL essentially as a scripting language. I am running multiple simulations, HB -> Optim -> HB etc. in succession as subsets of one large simulation. I need to be able to change the SimInstanceName[] after specific simulations within the overall large simulation are completed.

There is one ParamSweep component in the circuit.

Lou,

I have some more questions for you.

You mention that you are using AEL to run multiple simulations. There are several ways to do this.

One way is to make multiple schematics which are all ready to be simulated and then have all of them run in a batch simulation one after the other. This is also known as Batch Simulation.
http://edasupportweb.soco.agilent.com/portal/page?_pageid=34,37073&_dad=portal&_schema=PORTAL&id=8610

The other way is to take one specific design and then activate and deactivate specific parts (or simulation controllers) using AEL and run subsequent simulations.

Another way is to have all Simulation controllers active at the same time and run a simulation.

And yet another way is to have all the Simulation controllers active at the same time but use the ParamSweep controller to control the order in which the simulations run!!

Depending on which method you are using, a different approach can be taken to sweep your variable.

You could use a ParamSweep controller to control which simulations are run and also to control the sweep values of your parameter.

Or you could write if-then-else statements which can automatically set your value for SimInstanceName.

Or one can just have multiple ParamSweeps each one pointing to a different simulation controller and then activate and deactivate the right paramsweep controller at the right time.

If you would liek to discuss this in more details it may benefit to contact your local tech support office.

Thanks

Thanks for your reply,

I can't find a description of the desim_foreground_simulation_running (or de_sim_foreground_simulation_running) which is contained in your usermenu.ael file. Is this an AEL command or some other sort of ADS function?

desim_foreground_simulation_running() is an internal AEL function. It is NOT supported and therefore NOT documented..

The only information that i have about this internal function is that it returns TRUE if an active foreground simulation is running, FALSE otherwise.

Is the ael function :

desim_foreground_simulation_running()

usable in ADS 2004 ?

Lou,

I am assuming that you are using ADS 2004A Early Access. I tried the following command on that version of ADS in the Tools > Command Line window

de_info(desim_foreground_simulation_running());

It gives me appropriate False and True results depending on if the simulation is running or not.

So yes I do believe that desim_foreground_simulation_running() is usable in 2004A.

Do you have a case where it is NOT usable?? Maybe I can investigate it if you supplied me with an example.

Thanks

Thanks for your reply,

I am not using 2004A. My interest was only to address potential future issues.

Appreciate the help,

It is possible the Design "Sequencer" controller may be helpful to you. 8)

There is an example project...
browse to: %ADSroot%/examples/Tutorial/Sequencer_prj

Other examples too in...
%ADSroot%/examples/Connected_Solutions/3GPP_BER_prj
%ADSroot%/examples/Connected_Solutions/WLAN_BER_prj

The sequencer was new in ADS 2003C, and it is capable of much more general use than instrument connected solutions.

fwiw ::)
