probing internal bus

What are those blocks to the left of each "bank" that seem to be (I think, it's hard to see with the resolution) connected to the deepprobe points? Obviously if you are just "probing" the outputs (e.g. plotting in ADE) you don't really need to use deepprobe for that; only if you want to make a connection into the lower level cell (e.g. inject a signal or add a load of some sort) do you need such a probe.

Those blocks are multibit blocks from analogLib. Yes, I would like to inject signal, i.e., voltage in this case.
I have been walking with small stones in my shoes as well with probing/reading post layout results, but that is another story.

Dear delgsy,

I would like to probe 4 internal 8-bit buses from the testbench hierarchical level in post layout simulation.

As Andrew noted, if you simply want to observe the 8-bit buses within the hierarchy of an extracted view based netlist the use of a deep probe is not required. The same syntax you use for your deep probe instance to identify the internal net name can be used in a separate text file with a save statement that you can include in your netlist file.

I don't know if you considered this option or if you feel it might be "a better solution". however, adding or removing an internal net to observe with a text file seems faster than making a schematic change to add or delete deep probe instances - at least from my perspective.

If you are not familiar with how to use an include statement in ADE to add one or more save statements, There is a Rapid Adoption Kit (RAK) entitled "Using Spectre SAVE Effectively: RAK" that provides a good review of selecting saving nets in a simulation that also details the use of a file to contain the save statements (i.e., Action 22 on its page 19). The RAK is at the On-line support portal at URL:

Of course, you have probably read the short article on the syntax required for a deepprobe instance at URL:

I hope I understood your question and that Andrew's and my suggestions provide some added insight delgsy!
