I'm using IC5141ISR20110503, MMSIM126.96.36.1991.isr6, and INCISIV12.10.3
I have been able to get deepprobe to work with AMS(APS) using OSS through the ADE, however it requires modifying the resulting netlist.vams located in the simulation's "netlist" directory. The toplevel netlist located in the netlist/ihnl/cds* directory has an iprobe line:
x1 (x0.n0 n1) iprobe
However when this makes it into the netlist.vams file, which is what AMS uses when running, it looks like:
iprobe x1 (\x0.n0 , n1);
The hierarchical name has a \ placed at the beginning of the name which causes it not to work. Deleting this \ and rerunning without renetlisting allows the net to be accessed hierarchically. There may be an option to stop this \ from being added, but I don't know what it is. Until then, hand editting is a reasonable approach.
