Custom Signal probing options in ADE-L

It depends on which IC subversion you're using (which is why the forum guidelines ask you to provide this rather important information). In recent versions, you can use Outputs->Save All, and then there's a "Save by Subckt" tab on that form:

You click in the instance box and select the instance on the schematic. You can then type in how many levels of hierarchy to save underneath that hierarchical instance in the box next to the checkmark in the V [depth] column.

In older versions, you used Outputs->To be Saved->Select by Subckt (or something like that) and it opens a tab in the outputs section in the ADE L window. The use model after that is essentially the same though.

So you might need to set lvlpub to save the top two levels, and then use this mechanism to specify additional blocks to save.

Andrew. 

Hi Andrew,

Sorry I am adding the version now : "IC6.1.7-64b.500.15"

The second way you described almost works for me. I go to "Outputs->To be saved->Select by Subckt Inst"

Then under the V[depth], if I tick checkbox and just leave it blank (no number), the sim saves all wave-forms at all levels of the hierarchy of my instance xlogic. But if I make V[depth]=1 (or 0 or 2), none of the signals are saved either at level 1 or at any other level of my instance 'xlogic'.

I tried this with spectre and AFS simulator with the same result.

In "Outputs -> Save all" I chose the lvlpub option and made nestlvl=3  

If I take a look inside the netlist file the netlist translates this at the bottom as:

-----

save I22.Icore_top.xlogic.* depth=1 compression=yes

saveOptions options save=lvlpub nestlvl=3

----

Do you have any suggestions on how I can make the V(depth) option work as intended (save specific layer but not the layers below it)?

Thanks

Something appears to be not working correctly with the depth option - I either get nothing or everything, and it also depends on whether the wildcard is present or not (a difference in behaviour between the older version you're using and the version I'm using).

I won't have time to investigate and debug this and then work with R&D to address (I'm travelling at the moment), so I would suggest you report this to customer support.

Thanks,

Andrew

Ok - thanks for confirming the problem. I will get in touch with local Cadence customer support.
