When working with complicated schematics in ADS it helps a lot to show only the relevant parameters of all components. Im using quite many Multilayer transmissionlines, and basically never use external RLGC files. Therefore it would be nice not to display this parameter. Same for the Component name ... this is ususlly nor relevant, so I switch the display off. Is there a way to change the standard settings for the displayed parameters of such components ?
Yes, it is possible to change the default values as well as which parameters that are displayed etc for the built-in components in ADS. BUT, it does involve editing the component definition in AEL. The component definition may change in the next version of ADS for any given built-in component, so there is a risk that you may have to redo your customization work for the next release of ADS.
Here is how you do it:
1) Locate the AEL definition for the component(s) that you wish to modify. The AEL files are located in $HPEESOF_DIR\circuit\ael\examples. There are many AEL files here, each representing a type of components. For instance, all multi-layer components are defined in the file ckt_mlyr_item.ael
2) Copy the file that you wish to modify to any folder of choice.
3) Edit the copy of the file and change the parameter values, visibility etc. For instance, if you want to hide a parameter from the schematic by default, add "| PARM_NO_DISPLAY" to the third argument in the create_parm() line. Here's an example with the ML2CTL_V component. "| PARM_NO_DISPLAY" is added to two parameters, RLGC_File and ReuseRLGC:
3) To use this modified component definition you need to load teh AEL file. You can do it manually from the AEL command line, or configure ADS to load the file automatically when ADS starts.
Manually from command line:
ADS Main Window Tools > Command Line... Type this command:
load("path to modified AEL file");
Hit Apply Place a ML2CTL_V component on the schematic - you should now find that the two parameters are hidden by default.
To load the AEL automatically at startup of ADS
Modify the configuration variable SITE_AEL or USER_AEL to include the folder where you keep your modified AEL file(s). Example:
(Note the slash at the end of the path! It's required to identify that this is a folder. ADS will load all AEL files in this folder. If the slash is omitted then ADS will try to locate a file with the specified name and load just that single file)
Restart ADS. The changes that you made should be applied every time you start ADS.
I just learned, that basically the reuse RLGC option is quite useless for me, as it seems to be not supported to use any external (Spice) RLGC matrices. 1) is this really true ? So far we expected after some normalization we can use external RLGC files for simulation! 2) if the RLGC option is that useless, can it be changed, that the Display option is set to "switched off" in the next ADS release by default ? 3) In the "Open your eyes" seminar I attended I asked on using Spice RLGC files in ADS. The answer was, that this will be supported in one of the next releases. So basically this is not just an update on the current "feature", but some complete new option ? Do you have any idea in which release we are going to see this feature ?
