Hi! I am trying to run a triggered PNOISE analysis on a extracted design using a DSPF view, but I'm unable to specify in ADE the triggering nodes.
In my original PNOISE settings (run over the pre-layout schematic) the trigger event is defined on the following nodes (which I selected with the mouse on the schematic view):
/DUT/LATCH<5>.vOUTp and /DUT/LATCH<5>.vOUTm
which the netlister translates into the following directive in the netlist:
pnoise pnoise start=SIM__FREQDOMAIN__Fstart stop=SIM__FREQDOMAIN__Fstop \
dec=SIM__FREQDOMAIN__Npoints_per_decade pnoisemethod=fullspectrum \
noisetype=sampled measurement=[pm0] annotate=status
pm0 jitterevent trigger=[DUT.LATCH\<5\>.vOUTp \
DUT.LATCH\<5\>.vOUTm] triggerthresh=(PNOISE__vREGENd) \
triggernum=1 triggerdir=rise target=[DUT.LATCH\<5\>.vOUTp \
DUT.LATCH\<5\>.vOUTm]
However, when I try to switch to the DSPF view for my DUT (using a config view), I cannot specify anymore the above nets for defining the PNOISE trigger.
I tried, without success:
- To manually type the node names in the ADE PNOISE dialog; but when I press the "change" button, ADE complains (e.g. "Couldn't find net named "DUT.LATCH\<5\>.vOUTp" in the design")
- To copy the pnoise analysis definition in a text file and pass it to ADE as a .scs model file; but the netlister includes it in the netlist before the PSS definition, so Spectre ignores it (because it didn't run first a PSS)
Any helps is greatly appreciated!!!
Thanks and regards, Jorge.
P.S. Apparently someone had the same problem long time ago:
