i have problem with characterization of complex cell.
my cell is complex & i can't use one ff or latch!
my cell.otp:

output result:
reading /home/.../TD_X1.opt...
Error: statetable(D L2 CKM CKLC CKL2 RET,IQ IQN) is not a valid group of cell. (NCXPS-22)
correct errors in /home/.../TD_X1.opt and rerun

cell types:
combinational : 1
pruning inactive cells...[0] done
done
Error: failed library database initialization (NCXDB-5)
-----
my ncx: Liberty NCX version C-2009.06-SP1
i think i can't use "ncx_multiple_descriptor".

I'm sure I'm doing something wrong, but don't know exactly where it is.

Thanks in advance

Characterize Transition Detector

I make it simple.
MY Transition Detector can model with 2 FF, like this:

d.png

I use this state table:
statetable ( "CLK D", "IQ IQN"){
table : "H - : - - : H L ,\
L L/H : - - : N N ,\
L r : - - : L H ,\
L f : - - : L H ,";
}

BUT the answer is:

cell subUTSI_090nm_0V30::TD_X1 (1 of 1) (2in/2out pins)
Error: Unsupported cell type (multiple clocks CLK D). (NCXSN-24)
Error: failed sensitization
done
