skill code to toggle waveform visibility

Hi Dan,

Currently there isn't really a SKILL API to do this (certainly nothing public, and even amongst the private stuff it isn't really quite what you're after). I have an outstanding action to make a requirement specification for a SKILL API for ViVA that takes advantage of the way things are done now in ViVA rather than trying to bolt it on to the old awv API. Whilst out for a walk this afternoon (it's a public holiday here in the UK), I was thinking this through a bit more and have an outline in my head. Won't help you now, but at least it means that hopefully I'll have a proposal soon for R&D to consider.

Anyway, thanks for your post - it might have finally pushed me to getting this done!

Regards,

Andrew.

Thanks for the quick reply. I'm not surprised that currently I can't quite get there from here. There seemed to be too many gaps. I'll look forward to something in the future.

BTW, if you'd like some customer review/feedback on any proposal, I'd be happy to look it over. In general the ViVA skill API could certainly benefit from an expansion. There are some things like my initial question where having a skill way to do what the GUI can currently do would be nice and there are some other places where you just can't do it at all but it would be nice to see. One example of this latter category would be a hook for defining a function that goes between the tracking cursor and marker reading a value and what is displayed. A simple textbook case would be on a smith chart to convert between reflection coefficient and impedance or admittance but I've had some other non-textbook cases where I had a different mapping function. Custom grids would be cool too. A textbook example would be a Nichols chart and I have a non-textbook example that is of some interest.

Enjoy the holiday.

Hi Dan

I did some search, and quite lucky find an API to hide/show the waveform. It's:

awvSetWaveformDisplayStatus(
w_windowId
x_waveIndex
g_enable
[ ?subwindow x_subwindow ]
)
=> t / nil

you may use "awvGetCurrentWindow()" to get the waveform w_windowId;
and use "awvGetWaveNameList(w_windowId)" to have a list which contains the "x_waveIndex" for all the waveforms in the current window.
and then "g_enable" is used to control show(t)/hide(nil) the waveform.

I give it for a try, it works.

You still need to find the APIs to get the waveIndex for the selected waveforms.
According to my colleagues' script, it's feasible. (I did not check the source code, but his script interacts with the selected waveforms)

Good luck.

Yi,

*mild embarrassment* Thanks for spotting this - I'd completely overlooked this function. Unfortunately because of the inconsistency of the API, plus many old functions that no longer work - I'd missed this altogether.

I'm not sure of a way of getting the selected signals though. Maybe I'll be embarrassed again, but CCR 1334459 is asking for this (along with a bunch of duplicates) which leads me to think there isn't a public API (couldn't find a private one either).

Regards,

Andrew.

Hi Andrew

Thank you for the reply. I was just lucky to find such expression.

I really admire your ability to manage all of these SKILL APIs, it's a huge effort to do this.
And your precise answers in the posts are really helpful. I am impressed about all the details you listed there.
I'd like to follow you and make some contribution to the community.

I take a look at the source code from my colleague. There is no API to get the selected signals.
It's my wrong assumption.
Actually, he import all the signals from the ViVA into a form, and then do the selection there.

I assume this is not what Dan want.

Hope to see some new public APIs from ViVA itself. Most of them are private right now.

Best Regards

Yi

Andrew if it makes you feel better, I read through the full list of functions for ViVA and also missed that one. I'm also always impressed at how much you can keep on top of!

So actually, this is pretty close to what I was looking for because my intention was to just turn them (the waveforms) all off and then manually turn on the ones I wanted to see at any time. With the combination of the functions Yi suggested, I can do this but I do see one artifact and that is the eyeball icon in the visibility column does not seem to get updated to match if the waveform is actually visible or not.

Hi Dan

I just try to repeat the artifact you have mentioned.
It's strange that in my place the "eyeball" icon is updated accordingly.

I am using cadence version 6.1.7.500.6.

It might be a reason for our difference.

Best Regards

Yi

When I tried this yesterday (with 6.1.7.500.11) the visibility indicator in the legend was also updated. What subversion are you using Dan?

Andrew.

That is probably it. I'm on 6.1.6.500.13.2. I need to get a more recent 617 installed and this is another reason.

Dan,

I did just try:

foreach(num car(awvGetWaveNameList(awvGetCurrentWindow())) awvSetWaveformDisplayStatus(awvGetCurrentWindow() num nil))

in 6.1.6.500.14 (I have this version to hand) and that worked OK... perhaps it really was just a temporary blip?

Andrew.
