how to save the current display layers using SKILL??

Hi Howard,

Are you trying to save the display setting for LSW to a display.drf file? You can just use command  drDumpDrf to dump out the drf info to a file.

Hi How..

Thanks for answering my question.. But it seems the SKILL command drDumpDrf doesnt do what I want.. 

Here is what I want:

example:  In a layout, I have M1, M2 and poly layers visible and I want to save that setting . I can do that manually by

From the LSW window-->Edit-->Save--> ( I can save it to a file).. Now if I want to load up that setting, I can do: drLoadDrf("file"),

it will load up my setting properly..

The SKILL command drDumpDrf will save the setting to a file but when I try  drLoadDrf("file"), it doesnt load up my setting properly..

 Thanks for your help

Howard

Howard,

drDumpDrf and drLoadDrf are nothing to do with what is visible or not - that's just saving the display resource information (packets, colors, line styles etc).

Which version of the tools are you using?

Hi Andrew;

The OPUS version I am using is 6.1.5.. 

Please show me on how to save the current layers setting by SKILL command.. Now, I only know how to save the setting

manually by: 

LSW->Edit->Save-> (save to a file) then load it up by: drLoadDrf("file").. Quite tedious..:(

 Thanks

Howard

OK, you must be using the old LSW (not the layer palette?). The function to save the LSW info is a private function.

BTW, you should use load() not drLoadDrf() to load it...

However, which aspects of what's in this file do you really want?  Maybe I can just write a cut-down version?

Regards,

Andrew.

Hi Andrew;

You are right.. I am not using the layer pallette.. I like to have the separate LSW window..

I just want save the current visible layers I have in the LSW then load it up again when I want ..

Example: in a layout I have M1,M2, and poly... After a while, I want to have those layers again, I can go

to the LSW and turn those layers on again.. But that's not efficient way..,, So if I can write to a file of those

layers and then load it up whenever I want would be great..:)

 Thanks

Howard

Hi Howard,

Have you tried the Layers Palette?  This can be undocked or unattached from the layout window (in IC616 we can have the Palettes synchronised between all layout windows, or one-unique-per-window Palette).  The reason I say this is that the Palette extends the LSW Layer Set capability quite considerably, and it sounds as if it is this Layer Set feature that you need - to save which layers you have in the Palette/LSW.  You can not only save which layers, but also whether they are visible or selectable too (again, IC616 further extends the features available, such as other objects, e.g. the ruler).

Hopefully the features you need are already built into the tool.  Can you take a look and let us know if it meets your needs?

Regards,

Lawrence.

Here's some code I threw together (not really tested thoroughly) to dump the info. See the comments:

/* abDumpLayerAttributes.il

Author     A.D.Beckett
Group      Custom IC (UK), Cadence Design Systems Ltd.
Language   SKILL
Date       Sep 10, 2013 
Modified   
By         

Function to save information similar to the "save LSW info"
menu in the LSW or Palette 

Call:

abDumpLayerAttributes("./dump.file")

To load the resulting file, use:

load("./dump.file")

Note that there is probably an assumption that the layout window
is open before doing this...

Also, the object settings have not been thoroughly tested, so
apologies if there are any typos in the object names.
