How can I make only selected objects visible in a layout irrespective to layers

 if this is about instances then you may want to refer "View Level Functions" in skdfref.pdf

thanks babji,

My problem is different than view levels. the prob is If i select a set of figures in a layout then no matter what layer are they only those layers and figures should be visibe in my layout. is there a function to do so?? if not can you help me in finding a way to do this.

thanks

 Nothing that i know of in IC5141 for this. If you are not using IC6 then use a mixture of both view level functions and Ctl+t. 

Thanks Andrew,

It worked well on IC613. But, is there a way to do this in earlier versions?? Iam Asking you this because i have written a code to extract connectivity of a net which is global for all versions. what i require is, when the connectivity is extracted i have to make only that net visible and the rest invisible.

If not a direct function like dimming could you guide me how this can be done?

thankyou

Hi Harish,

I don't think it's directly possible. One way would be to use the "Hilight" functions (e.g. geCreateHilightSet(), geAddHilightFig(), geAddHilightPath() etc), to create a highlight on a particular layer purpose pair (or purpose pairs), and then turn off the visibility of all LPPs except those you've used in your highlight.

Andrew.

I have done what Andrew described and it works well in all versions of Cadence. I have implemented it in two ways. The first and simplest way was to use one hilight layer for all of the shapes on the net. However, when you turn off visibility of all layers, you cannot see which layers are used in your net. The way I prefer is to hilight each layer in its own color. I did this by defining layer packets for some unused lpps. Layer packets describe the color, line style and fill style for a layer. I chose the Unrouted and designFlow system layers (they have 10 lpps each and exist every technology file). For each of my metal layers I made a comparable layer packet using one of the designFlow lpps. For each of my via/contact layers, I made a comparable layer packet using one of the Unrouted lpps. I stored each of these mappings in a table.

For example:
hilightMapTbl["metal1"] = list("designFlow" "drawing1")
hilightMapTbl["via1"] = list("Unrouted" "drawing1")

When creating the packets, I used the same colors, but I made the fill pattern denser and the line style wider. These settings can either be done permanently in the display.drf or dynamically with drSetPacket.

When hilighting metal shapes, use the layer from the hilightTbl. If you turn off visibility of all layers, you'll still see your hilights. If you use a bolder pattern and line style, it kind of acts like a shadow mode. Your hilighted net stands out in context with the rest of your layout.

I hope this helps,

Derek

Thank You Derek

 It was a very good idea and it worked for me.

Thankyou once again
