probe analog/digital signals in AMS irun

[shun-qian@ti.com]

I'm running into troubles when probing analog signals when doing AMS
irun simulation. The testbench is setup as SPICE top with some digital
subckt replaced by HDL specified in amsd{} block inside ams control
file.
I'm probing signals inside probe.tcl file. However, I'm not able to
probe any signals inside analog domain.

It reports error like as below:

# Successful create probes for digital signals
ncsim> probe -create -database waves {xcounter.*}
Created probe 3

# Fail to create probes for analog signals inside xpll_top
ncsim> probe -create -database waves xpll_top.*
ncsim: *E,PNOOBJ: Path element could not be found: xpll_top.


Anyone saw this issue before? Thanks!!!
