Problem netlisting AV_Extracted from QRC extraction

Svilen64
Hi,

Netlisting fails when using AV_Extracted views for some cells, but not all.

The netlist error is:

ERROR (OSSHNL-378): Cannot descend into the view 'spectre cmos_sch cmos.sch schematic veriloga ahdl pspice dspf' specified for library 'basic' and cell 'ipin' in the 'View To Use' or 'View list' fields of config '...' for the instance '_qrcPin5' in cell '.../av_extracted_rc_coupled'. Modify 'View To Use' or 'View list' to contain an existing view. The variable 'hnlConfigMissingViewAction' can be set to "warning" or "ignored" to decrease severity

Setting the variable does not help.
config is set up with template "spectre"
opening up the AV_Exracted in layout viewer and searching for the instance gives no results

dspf output of QRC does not have this problem, but instance/net names are obfuscated and not usable in parasitic editor.qrc log header:
Cadence Quantus Extraction - 64-bit Parasitic Extractor - Version 23.1.1-p051 Thu Feb 15 21:25:45 PST 2024

Any clue what that _qrcPin5 is?

Thanks

Svilen


  • Svilen,

    I found some reports of a similar issue (it seems that something is creating instances of pin cells in the av_extracted view) and in both cases it pointed to something in the libInit.il of either the library you're using or the technology library. Unfortunately in both cases no more detail was recorded (and this was from 9 years ago, so finding out more detail is unlikely to be possible).

    Probably best to contact customer support over this (submit a case after logging in).
