ViVA Customization using .cdsinit

Hi Kevin,

> I still don't know why the line thickness and style lines don't work though.

Have you looked at solution ID 11806952? This solution addresses the methodology to change the  default style/color/thickness of waveform/trace in Viva in IC615. The solution walk you through how to modify your techfile or display.drf file.

In addition, if you are trying to set font related variables in your .cdsinit file, there is an API that needs to be called as I found out in a recent support issue. The syntax follows:

; Added from Wayne Ingram's note on 7/24/2013
;
; If customer is setting font related cdsenv variables in .cdsinit (via envSetVal API),
; there's a requirement to load the 'viva' context _before_ any envSetVal call is made.
; This can be achieved by the following in the .cdsinit file:

loadContext(strcat(prependInstallPath("etc/context/") "viva.cxt"))
callInitProc("viva")

; Now you can set font related variables...

envSetVal("viva.graph" "titleFont" 'string "Clean,12,-1,5,55,0,0,0,0,0")
envSetVal("viva.axis" "font" 'string "Clean,12,-1,5,50,0,0,0,0,0")

Hope this helps Kevin!

Hi Kevin (again),

I noticed that the later suggestion is now covered as Solution ID 20138670.

Hi Kevin,

One other point...I also found that some environmental variable settings are not implemented yet depending on the version of Cadence you are using. Those that were not implemented were commented out in the sample .cdsenv file found in the respective install directory. As an example of its location for one version of the Cadence tools, the sample .cdsenv file is at:

/tools/cds-6.1.6.7/tools.lnx86/dfII/samples/viva (./tools.lnx86/dfII/samples/viva/.cdsenv)

Kevin,

When plotting signals from ADE, the lineThickness and style aren't used - this is because you want the colours and line styles to match how the net is probed on the schematic, so instead the layers y0-y9 are used and you have to control their appearance using the display.drf . This is in the first solution that Shawn mentioned:

Hi Andrew,

I have run into the same problem that I want to use the solid and thick line to display in result browser.

But, I try to add

envSetVal("viva.trace" "lineThickness" 'string "thick") and envSetVal("viva.trace" "lineStyle" 'string "solid") in .cdsinit, but it fails

and I also try to

modify the y0-y9 in CIW -> Display Resource Manager, it also fails.

Please tell me how can I do it in .cdsenv.

Thanks in advance

Sincerely

Daniel

Hi Andrew,

I find that while I set the outputs and that the results automatically plotted after simulation.

And the setting I do in the .cdsinit works though.

Could you please tell me what is the difference between these two operation?

How can I change the setting as for the "Direct plot" do as similar to "automatic plot" do?

Appreciate

Daniel

Daniel.

Signals are plotted using the line style for y0-y9 drawing. You've modified the flight purpose which is not the right purpose (unless in that technology they use the same packet for both, but it seems unlikely if it hasn't changed).

The cdsenv settings in the .cdsinit are affecting any expressions plotted. The idea (I may have said this above, I didn't check) is that signals use a layer-purpose so that the schematic can be probed in the same colour/line style as the waveform. For an expression output there's no schematic correspondence, so that doesn't need to try to match it up to the schematic and hence it will use the viva environment variables to determine the line style.

Regards,

Andrew.
