LSW in cadence virtuoso

 Hi Hazo,

If you are using the IC614 version (or soon the new IC615 version) you can use the Layer Palette which gives (most of) the functionality of  the LSW in a dockable/detachable "assistant".  If you are using IC614 you will see the LSW by default, but you can enable the Layer Palette using an environment variable in your Unix window before starting "virtuoso":

setenv CDS_USE_PALETTE

The Layer Palette will be on by default in IC615, so you only need to set a variable for IC615 if you wish to use the LSW instead of the new Layer Palette.

If you are using IC5141 then I don't think that there is a way of doing this...

Lawrence.

If you are using 5.1.41, you can set a bindkey that calls:

leRaiseLSW()

This will set the spacebar to raise your LSW:
hiSetBindKey("Layout" "<Key>space" "leRaiseLSW()")

This will at least pop it above your other windows.

Good point Derek.

That makes me think that you could get the LSW to appear on the edge of a Layout window by using the leSetLSWBBox() SKILL function; also with a bindkey you would work out the layout windows' coordinates, set the LSW coords to be next to it (one side or other, your preference) and ensure that it is raised using the leRaiseLSW() function that Derek mentioned. So this might loosely simulate part of the docking behaviour, but the LSW window will not be stuck or attached to the layout window in any way.  You might also need to call leDeiconifyLSW() if the LSW has been iconified?

Lawrence.

 Hi,

I am using virtuoso 6.1.2 and  I am not sure how to bring Layer palette visible (where do i select it)? 

regards,

Hazo

Hazo,

The layer palette was (as Lawrence said) introduced in IC614, so the version you're using is too old.

Andrew.

well old style LSW was not that bad. I like focus follows mouse policy. With LSW I could change the layers in the LSW move back to the layout and use layout keybindings again. With the layer palette that is not possible any longer because I have to click into the layout window to get the focus. So here are my questions:

1. Is there a focus follows mouse policy for IC614?

2. Alternatively: How can I switch back to LSW?

Kind regards, Martin

Hi Martin,

In addition to Marc's answer, you can switch back to the LSW by removing an environment variable in your Unix window before you start the Virtuoso tool, in the IC614 release, something like the following:

unsetenv CDS_USE_PALETTE

In IC615 the variable has changed, since the default in IC615 is for the Layer Palette to be on, so in IC615 if you want the LSW you would need to set the following instead of removing a variable:

setenv CDS_PALETTE_OFF 1

(I don't think the value matters, just that the variable exists.

Hopefully this answers your questions?

Lawrence.

But bear in mind that it is quite likely that the LSW will be completely gone by IC616, as it makes a lot of sense to finally rid the tools of code which uses Motif libraries. If there are vital things you are missing with the new palette, please contact customer support and let us know.

Andrew

Marc, Lawrence and Andrew, thank you for your incredibly fast replies. Marc's solution is pretty much what I want. Sure, Motif libs are evil and will vanish in the near future.
