leMarkNet highlight options to high light in a subcell at 0 stop level

Paul,

I assume you want the display set to stopLevel 0, but want the marking to be throughout the hierarchy? You can do that with:

leMarkNet(point ?stopLevel 32)

I did think initially you might have to do dbOpenHier(cvId 32) but it seems that using the ?stopLevel 32 has the same effect.

Regards,

Andrew

Here are the options I use on the leMarkNet
leMarkNet(xy
?startLpp list(lab~>layerName "drawing")
?startLevel 0
?stopLevel 32
?thickLine t
?markNetColor mNet
?optionFile markNetFile)

If it something I have to live with of viewing other than at 0 level I can adjust.

I was just looking if there I was something I was missing.

Hi Paul,

Which sub-version of Virtuoso are you using?

Hi Paul,

I just checked, and this worked fine for me in that sub-version. I opened this design, left it at level 0, and then did:

leMarkNet(xy ?startLpp list("Metal3" "drawing") ?startLevel 0 ?stopLevel 32 ?thickLine t)

It takes a while as it loads the remaining levels of hierarchy into memory, but then I get:

The yellow highlights are nets inside the blocks (mostly). I did it with a ground net too, and it makes lots of highlights.

Perhaps I've misunderstood what you're asking for?

Andrew

Now that I know it can be done, I will see if there is something in my marknet file that is stopping the hilight

Thanks for the info

When I try with 0 stop level with the command
leMarkNet(enterPoint() ?startLpp list("M1" "drawing") ?startLevel 0 ?stopLevel 32 ?thickLine t)

*WARNING* (LE-103025): There is no valid shape at the specified point so tracing is not possible.
Specify a new point value that contains a valid shape.

Hi Andrew,

Did you use the code  to get the highlight like above?

Is it only showing the Metal3?

No, because that's not what Mark Net does. It is showing the whole net. The ?startLpp merely narrows down the layer to use as the starting point at the specified coordinates (there might be multiple layers at that point, which might be on different nets). It then follows the net (using the information in the tech file by default to determine which via cut layers are used to connect one layer to another, plus stop layers, and so on) and highlights the entire net - not just a specific layer.

Andrew,

I want to highlight a specific node(or net and pin), how can I do it?

For example, I would like to see the connection from active to metal 3. This some specific node. It is not a area.

I can't use the code above because there is no much metal3 in the area.

The option I used  a Top to current, and I set it to start 0 stop1. And when I clicked on the node, only metal1 to metal2 were highlighted.

But this is not what I want. This is because the corresponding node is also connected to active and poly.

Please help me.

Jake

Jake,

Mark Net is intended to follow a net from a specified coordinate, regardless of whether the database has connectivity - it follows the shapes to determine connectivity itself. Because the data may not have connectivity, you specify a coordinate to start from, not a net.

If you have data with connectivity already present (because you're using a Layout XL flow), then you could use Options->Highlight to increase the Hierarchy Depth, and then in the navigator go to the nets section, find the net you want, and do right mouse->Probe.

It's really hard to understand your setup or requirements. I'd suggest contacting customer support so that an application engineer can actually see something and give you relevant advice. I've just realised you've edited your post since you first posted it, but either way I can't quite picture your setup - hence my advice to go to support.
