what is the best way to measure current flowing at a node of a transistor in the rcx extracted view .
do i need to create a probe point in layout ?
Hi AnkurYou can do an out-of-context probing using the schematic view.- Create a config view for the testbench schematic- Run spectre sim using av_extracted view- From config view, descend into schematic view of the av_extracted view instance and do probing on the schematicPlease refer to $CDSHOME/doc/paramsim/paramsim.pdf.Best regardsQuek
In reply to Quek:
Thanks for your reply.
i tried as suggested in the documents you recommended
i get the following error :
NFO: (PARA-807) The license Parasitics_GXL is not available
*Warning* no "IT" data for node "/PRE-AMP/M22/S"*Warning* no "IT" data for node "/PRE-AMP/M24/S"*Warning* no "IT" data for node "/PRE-AMP/M2/D"
do i need a GXL license for using this feature ?
In reply to ankurprg:
Hi AnkurI think you might be using an older version of IC615 and is seeing a licensing bug which has been fixed in IC615-500-6. Perhaps you can retry with any versions higher than IC615-500-6.Best regardsQuek
I am using the IC615.500.132 which i guess is the latest version.
just to explain it again , I am already using the "out of context" probing for voltage measurement but somehow it does not work for current measurement but on schematic level it works (is there some other setting which i have to turn on ?) ..my extracted view is called "extracted_rc_typical" in the hierarchy editor.
Second point : i tried to backannotate the parasitics (resistive too) by providing the DC simuation path but the backannotation of parasitics resistor also does not work ..i tried the setup as given in the documentation ( i can successfully backannotate the parasitic cap.)
