viva settings ADEL and ADEXL

Clidre

Hello,

I was used to ADEL and only recently I've been using ADEXL. I've noticed the viva settings I have for ADEL are not valid for ADEXL. More precisely, I have a custom_init file in my work directory with this code

callInitProc("viva")

envSetVal("viva.trace" "lineThickness" 'string "thick") 

So in ADEL I could see the waveforms thicker and save my eyes.. Now that I switched to ADEXL the waveforms plotted with the plot all button are thin! So it seems that custom_init file is not taken into account. Can you please tell me how can I set permanently the waveforms think in ADEXL? 

Thanks a lot!

    This is the same as with ADE L. The line thickness only affects waveforms plotted as calculator expressions or from the results browser. It does not affect signals. Signals are plotted using the colours and line styles from the layers y0-y9 - this is done so that the probe on the schematic is the same as the graph. Any outputs which are plotted as expressions use the native line styles and thicknesses in ViVA - such as the setting above.

    If you want to alter the thickness of traces plotted from signals, you need to change the definition of the packet used for y0-y9 in your technology, either by using the Display Resource Editor or editing the display.drf file.

    Regards,

    Andrew.

    Thanks! Could you please tell me how to set the waveforms thick?

    I created an empty file called display.drf in my local directory, but I don't know the syntax to set the waveforms thick.

    Rather than trying to figure out the syntax, it's much easier to use the Display Resource Editor to do this.

    Use Tools->Display Resource Manager (in the CIW) and set it to Application: Virtuoso, Tech Lib: your technology library (whatever that is).

    Set the filter to "y" (to pick the layers y0, y1 etc) then click (one at a time) the layers y0, y1 etc and for each alter the line style to a thicker line (note, you may need to move your cursor over each of the columns in the display resource editor to get it to refresh - this is a consequence of it being an old Motif-based UI; in IC617 it has been replaced with a newer, cleaner, better, Qt-based UI). Make sure you hit Apply after each change.

    Then do File->Save and save the display.drf in your working directory.

    Do note that whilst this display.drf would then (most likely) be picked up when Virtuoso starts, many PDKs explicitly call drLoadDrf() to load their display.drf which would override yours if this is done via the technology library's libInit.il file. You could always re-load (via the Display Resource Editor File menu, or using drLoadDrf("./display.drf") your file after that has happened if this is an issue for you).

    Regards,

    Andrew.
