Assura QRC run problem

emax

The Assura QRC run fails after LVS match. The QRC was setup using QRC -> Setup QRC
In the Setup tab all Output Formats are selected and Set As Default is Extracted View. The Technology and Rule Set is selected correctly using drop down menu and Template File is not selected.
For the Extraction tab all Allow Extraction Types are selected and Set as Default is RC. Nothing is changed in rest of the tabs. Selecting OK pops up a message to overwrite Template File /opt/<design kit installation directory>/assura_<design kit >_tech/rcx/.rcx_setup.tpl

Everything seems ok till now, but when QRC is run... a pop up message says: No technology directory found. and next the Run Form opens with Technology selection disabled. The QRC fails after run with the following error log

INFO (EXTQRCXOPT-243) : For Assura inputs, if the "output_setup -directory_name" option was not specified, it is automatically set to the input directory.

The actual name of pdk is replaced with <design kit> in the above log. I suppose some configuration is not correct as the same set of tools works fine with Cadence gpdk045. Please help to resolve this issue.

  • I'm pretty sure you are pointing to the wrong technolgy directory
    The file "RCXspiceINIT" should be taken from the technology directory.
    Have you checked if it exist in the directory mention in the info message and if you have read access to it?
    "INFO (RCXSPIC-27050): Could not open file /home/rusr/cds_130n/lvs_run/RCXspiceINIT"
    You probably should not overwitre the PDK setup template with your settings.
