Results Browser in IC5.10.41

Hi,

I am using IC5.10.41 and wanted to know how can the below mentioned things be done.

1. Is there a way to print the numerous output expression values for a simulation that was previously done? Till now i have found that they would need to be re-evaluated using the calculator, which is all the more troublesome if we have numerous corner or parametric simulations!!
I believe in IC615 its possible to reload these expression values as there is a resultsDB for the same. Is there something like this for IC5141?

2. Is it possible to plot a particular signal for all the corners/parametric sweeps, using the result browser? As currently i see we need to individually select each corner result for the signal and plot it

     Dear ag2888,

     > 1. Is there a way to print the numerous output expression values for a simulation that was previously done?

    If I understand your question correctly, and if the expressions are listed as "Outputs" in your ADE session, the results can be re-computed by loading the simulation directory into the ADE ( Results->Select...), checking the relevant "Plot" boxes adjacent to the Outputs you wish to evaluate, and then re-evaluating the results from the ADE (plot button below the run button).

     If the expressions are not listed as "Outputs" in ADE, you may add them and follow this process. If there are numerous cases to examine, save the ocean script (Session->Save Ocean Script..) and modify the script to loop through loading each of your simulation directories and print the relevant outputs to a file. Whenyou save the ocean script, your output expressions will also be saved at the end of the script.

     

    > Is it possible to plot a particular signal for all the corners/parametric sweeps, using the result browser?

     If you load the parametric results into ADE and re-evaluate the relevant output(s), they will be plotted as a family. I believe you need to use the Calculator, in combination  with the Results Browser, to plot a family of curves directly.

    I hope I understood your questions.

    Hi Shawn,

     Thanks for the reply. I still have a couple of doubts though.

    While reloading the simulation directory it should be the psf directory that we should be loading right? The reason i ask this is that i face difficulty in doing it.

    If i run a simulation (say corner sim) in the distributed mode then i can see a folder by the job name in the path - ~/simulation/<Sch_name>/spectre/schematic/Corners/job. This folder i can load from the window.  But if i run a sim locally then each corner has a separate folder in the path - ~/simulation/<Sch_name>/spectre/schematic/Corners/<corner_name>. And this does not even appear in the Select Results window!

    Same is with the parametric sweeps. Each is a separate folder how do i load them in these cases?

    I have attached the snapshot for the errors/warnings that i get when i try to load the psf folder itself.

    Hi ag2888,

     > While reloading the simulation directory it should be the psf directory that we should be loading right?

     When you are running in distributed mode, the name of the results directory is selected when performing a  Results->Select operation for a parametric simulation, for example. If you load a specific psf directory, that will load one of the specific results from your set of parametric sweeps. In local mode, the  ~/simulation/<Sch_name>/spectre/schematic directoy is selected to choose the parametric results.

    Having written this, I have occasionally experienced a problem when selecting parametric results where the ADE will not allow one to select the simulation directory of a parametric simulation - but only the psf directory of each of the runs within the parametric sweep. I have opened an SR for this a couple of times. The problem is intermittent, but does seem to occur when switching between distributed and local modes os job submission. If you experience it, you might try re-starting your icfb session and trying to select the parametric sweep directory again. This has worked for me a few times.

    I am sure others can provide further insight into your issue than I can.

    Hi Shawn,

    In the distributed mode i loaded the ~/simulation/<Sch_name>/spectre/schematic/Corners/job  folder. This works fine and does plot waveforms and expressions for all corners when i do a plot outputs.

     The issue is now for the locally run jobs. There even if i try loading the ~/simulation/<Sch_name>/spectre/schematic/ directory for the corner/parametric sweeps or even if i try to directly load the psf directory (for a single typical sim) it gives me the warning that no simulation data found.. And i have tried restarting the icfb a couple of times to check, but it still is the same warning. Have u faced this before?

     Also another weird issue that i am facing is that the results obtained for the simulations are different when i run the sim locally and in distributed host mode. Even though there is no change in the circuit or the sim setup.. Have u seen this kind of an issue before?

    Sounds strange. Whilst IC5141 hasn't been supported for more than 2.5 years now, this is the kind of thing that we can look at in customer support.

    Your second "weird issue" I just answered your other post.

    Regards,

    Andrew.
