Hi DG202504226528 . What version of the software and hotfix are you using? I tried to replicate it at my end (24.1 HF04) and was not able, so if it is a bug, it might be specific of your particular version.

Hi, I have a skill routine that I'd like to loop through the film files listed in Allegro's visibility panel view drop down list. Currently to get the list of film files I'm using axlGetParam("artwork")->groupMembers The issue is that the film file list also includes those that are toggled off for visibility in Film Domain Settings(see image below) In an attempt to find artwork visibility value, I used axlPrintDbid which has visibility under Domains but it seems to be dead end (see below) Any help is much appreciated Thanks, David Nguyen example axlPrintDbid on artwork object: c objType artwork c name XXXXXXXX a domains ("ipc2581" "pdf" "artwork" "visibility") a groupMembers ("PACKAGE GEOMETRY/SILKSCREEN_BOTTOM" "DRAWING FORMAT/GBR_SS_PN" "DRAWING FORMAT/GBR_SS_SH2" "BOARD GEOMETRY/SILKSCREEN_BOTTOM") a offset (0.0 0.0) a rotation 0 a sequence 23 a shapeBoundingBox 0.0 a undefineLineWidth 5.0 a vectorBasedPad t

Hi Steve, This method, is really bad. (Not shooting the messenger here ) , not your fault. :) Who would even know to right click on a drop-down list box ?, Honestly it is not credible LOL. It has been this way since they changed the 3d view back in V17.2. I never even knew that existed until now but did often wonder why changing colors did not work. Yikes. Thanks for the info. Best Regards.

Good afternoon, I'm having a small problem trying to compile my project in Orcad Capture. On the "Start Page" tab, I see "Files License Not Detected." When I try to open a project, it only appears in read mode. I don't know what's happening. However, my license is active.

Use: p = axlGetParam("artwork:SOLDERMASK_BOTTOM") p ->domains will return what is enabled. i.e. ("ipc2581" "pdf" "artwork" "visibility")

so that was what I was missing, thanks fellow Dave!

Currently we can show parasitics in Orcad and Allegro X by typing the command "show parasitics" in the command prompt. Now the user can select each cline they wish in succession. This calculator display appears to the user and will recalculate depending on the cline selection. Currently this functionality is not yet available in the Presto PCB Editor. .

Very thx,Saloni,it's good

This appears to me about the license, but I don't know how to change it because nothing related to licenses appears in the help tab.

You will be contacted by separate channel of communication in order to look into your licensing problem.

Hi there, I am trying to extract data from PSF files using Skill in either Ocean or Virtuoso. I have found the central psf directory of a multi-parameter Maestro simulation and use: openResults(psfPath) After some calculations, the results can be sent to a CSV file using: awvSaveToCSV(wave "/path/to/file.csv") However, I find that the column order of the data is wrong. I suspect that the column order is the order in which the simulations can complete - which isn't necessarily the same as the order they are started in. For example, the second column is associated with the fifth simulation. I could unscramble the columns if I had some reliable information on which column is associated with which simulation number. Can anyone make any suggestions as to how I obtain this information? Thanks for any help with this. Simon

Hi,friends I have an amplifier simulation circuit named TB , which contains an AMP module. The next hierarchy level of AMP includes modules like BG, OTA, and TRIM. Suppose the input of TRIM is DEC0 . Is there a way to place a voltage source at the TB level to control DEC0 across hierarchies without generating a PIN for DEC0 in intermediate modules? Hierarchy : TB → AMP → TRIM

Hi dogman4, Yes, you can place an analogLib deepprobe instance and specify where you would to like to reach as Hierarchical Node. And then you connect it to a voltage source. Regards, Alonso

function attribute for sequential cells are generally defined by users according to the behavior of the cell and the requirement from STA tools. A stand FF with Q QN as outputs may have, cell (myFF) { pin (Q) { function : "IQ" ; ... } pin (QN) { function : "IQN" ; ... } ff (IQ,IQN) { next_state : "D" ; clocked_on : "CLK" ; clear : "CLR’" ; preset : "PRE’" ; clear_preset_var1 : L ; clear_preset_var2 : L ; } } Guangjun

Hi，Alonso vrey thx，it‘s works

Hi - I have to agree but the good news is that the original 3d canvas has now been given an upgrade. From 23.1 onwards you get access to both the 3d Canvas and the new 3dx canvas (which I'm assuming will replace the original one). This has a Custom theme option which you can modify to suit. :-)

I've done a bit more searching - there's this: How to get corners name from ADE Assembler / XL simulation database using SKILL? (Requires Cadence Support Login) So this identifies the simulation "points" - and in the order I'm expecting - however it doesn't solve the problem. If one does openResults then awvSaveToCSV the columns in the data will be in random order compared to the order in the Maestro RDB file. Simon

Thank you for you reply. But i have a geometry generation code and want to couple it to Turbo using a genetic algorithm to do this optimization. Has it been done before? Any tips?

Thank you Frank for confirming. Thank you Andrew for making it work! I followed your guidelines and am able to make it work. I will check if I can get the model for Pspice.
