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

What do you mean..?

If you're asking me, then I was countering the fact that Paul said that Mark Net was not highlighting shapes in sub cells when the displayed stop level was 0, and that it was the situation when there were no pins present. I just showed an example where I had shapes in the lower level cells (not visible, because the stop level is 0) and those lower level cells and the top level don't have any pins, don't have any connectivity information, and mark net still is able to follow the shapes in the lower level cells.

So I don't understand what Paul's issue was in the first place, nor do I see that the presence of pins in the layout has anything to do with it.

What did you mean by "what do you mean?"?

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,

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.
