characterizing pex netlist using elc

KALYANICH

Hi,

When I'm running ELC to characterize pex netlist of my cells, i'm facing the following problem.

[WARNING(db_spice)]No spice simulation to do, please check the cell/process list for any error

But when i use the netlist from schematic simulations are running without any problem.

Following are the steps followed:

db_open AOI21X1
db_install -model ts18sl_scl.lib -subckt AOI21X1.pex.netlist

set_var SG_SPICE_SUPPLY1_NAMES "vdd vdd2"
set_var SG_SPICE_SUPPLY0_NAMES "gnd gnd2"

db_gsim
db_setup -s setup.ss
db_spice -s spectre -keep_log
db_output -r AOI21X1.rep -alf AOI21X1.alf -p typical
db_close
exit

Please help me if i'm missing anything in the process from pex to elc simulation.

Thanks.
