For the bulk of operating sims, I use the calcVal function in a way that passes data assuming that the trimming and post-trimming tests occur in the same run and sequentially: calcVal("Trim_VBG_best" "VBG_Trim" ?cornerName "Trim" ?defaultVal 0) But what I really need is for calcVal to pull info from the successful VBG_Trim test and pass it to the Troubleshooting rerun of the next test. The only way I see to do that is to separate the rimming run into a stand-alone simulation that writes its data, and then set up the calcVal reference to an already-completed test results, perhaps like this: calcVal("Trim_VBG_best" "VBG_Trim" ?cornerName "Trim" ?historyName "VBG_Trim_Only" ?defaultVal 0) where VBG_Trim_Only is the name of a stand-alone sim that only trims, but does not run post-trim sims. I have not yet searched for it, but I think there is some detail to making sure the Monte Carlo run sequence is the same for two separate simulations...this is necessary to make sure the trims correlate to the right post-trim sims. Is there a simpler way to make the Troubleshooting reruns pick up the calcVal info? And am I missing a step in getting this to work, as described above?

From 23.1 ISR 4 onwards PSpice A/D has been introduced with ability to support audio simulation. You can use this amazing feature and simulate audio input files used in circuit design and generate electronic/digital audio as output by using the WAVESRC component in PSpice. You need to place the WAVESRC component from Component Explorer window and add the following properties. Channel: Information of the channel Path of audio file (.WAV format) to be imported.

Unfortunately the step model was large (24MB) and it resulted in the symbol file of about 6MB. Recently I found another STEP model which is much smaller. I thought lets update the symbol with this new model, it will make the symbol file size much smaller. Unfortunately, the symbol file size remained almost the same. it seems that the space taken by the previous step model is not freed up. I looked in all the menus of Orcad pcb editor but I could not find any function to clean the symbol file size. I made a test by deleting all pins, shapes, step, and lines. I kept only the refdes and saved the symbol but still the filesize is a large 5MB. It seems that I have to redesign the symbol from scratch if I want a smaller file size. Anyone has a suggestion?

That is why it is advised to write SKILL files that only define procedures (except for what you call the "main" program) So they can be loaded and their procedures can be called individually In your case, you could write a function that parses the SKILL expressions inside a given file (usually this is done using `lineread') and only evaluate the S-expressions starting with `defun' or `procedure' but I would advise you not to do so as this is very unusual. https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-program/1398390#1398390Fri, 24 May 2024 14:32:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:1398390Mabr86/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-program/1398390#1398390 For example... Content of the sub-program: printf("test") procedure(greet() printf("Happy Birthday") );end procedure ... Now, in the main program I want to call the sub program above. But just the procedure "greet()" should be executed, not the "printf(test")". https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-program/1398389#1398389Fri, 24 May 2024 14:14:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:1398389AurelBuche/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-program/1398389#1398389 Hi, Your question is so vague... are you even talking about SKILL? An example of what you have and what you want to achieve would be welcome. Let's assume what you call the main program is Virtuoso and that you want to call a specific SKILL function. If you have a file like ~/skill/example.il which contains : (defun example_procedure () (info "calling `example_procedure'") ) Then yes, you can load this file in Virtuoso and then call `example_procedure'. CIW> (load (simplifyFilename "~/skill/example.il")) -> t CIW> (example_procedure) calling `example_procedure' -> nil If your file is not defining functions but running code directly, this can be very dangerous, as shown in the following example : The file ~/skill/example.il could contain (deleteFile ...) And when loading them you might erase files. https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-programFri, 24 May 2024 14:06:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:59455Mabr86/cadence_technology_forums/f/custom-ic-skill/59455/execute-only-the-procedure-of-a-program4 Is it possible to only execute a specific procedure of a sub-program when opening this sub-program from the main program? https://community.cadence.com/cadence_technology_forums/pcb-design/f/allegro-x-scripting-tcl/59443/exporting-variants-lst-through-tcl-or-automation/1398388#1398388Fri, 24 May 2024 13:52:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:1398388PatEscher/cadence_technology_forums/pcb-design/f/allegro-x-scripting-tcl/59443/exporting-variants-lst-through-tcl-or-automation/1398388#1398388 Hello Vishwajeet, unfortunately this brings up the UI which requires a user input.

If you do it the way that you're doing it, it won't have a difference any time the code is loaded beyond the first time, because there's a check to see if the variable is set before setting it to the default. Which version of CCSinvokeCdfCallbacks are you using? There's a version number at the top in the comments with a "SCCS" line. In the latest it is not using the effective CDF by default, so I would be slightly surprised by the warning message at the bottom of your last post. Andrew
