Tools and Tech:
ST 65nm | LIBERATE Library Characterization Platform (x86_64) 12.1.4 (altos 121) | Cadence Virtuoso 6.1.5-64b | Calibre Interactive - PEX v2012.4_16.11
I am trying to characterize a full custom designed cell.
- Parasitics are extracted using Calibre Interactive - PEX v2012.4_16.11. The extracted netlist is CELL.pex.spi from pexRunDir using Calibre PEX tool.
- Technology Model Files created using: ADE L environment --> ArtistKit --> Setup Corners ... --> Model File --> Show Corners --> File --> save as ... which is corners.scs for spectre simulator
The problem is that Liberate tool does not write any *.lib file out and no error or log file is generated by Liberate so that I can find the issue out?
Any Idea how to proceed or solving the issue?
Any better or even the corret way of getting extracted netlist and model files?
The simple script which I use comes from example codes of liberate and Virtuoso Liberate Reference Manual 18.1
set ROOT "/home/PROJECT"
source ${ROOT}/PATH.tcl
source ${CHAR_SCRIPT}/parameters.tcl
set MODEL_TYPE spectre
set_operating_condition -voltage ${my_voltage} -temp ${my_temperature}
source ${CHAR_SCRIPT}/template_example.tcl
read_spice -format spectre ${CHAR_MODELS}/${MODEL_TYPE}/${MODEL_TYPE}_corners_ss.scs
set spicefiles ${CHAR_NETLIST}/Inv.pex.spi
read_spice $spicefiles
