Netlist Error in Virtuoso IC 5.1.41

[CarlPavano]

Dear All:

In IC 5.1.41, I create a cell which contains a pmos with length = pPar("Pl") (use passing parameter).

In ADE, I generate the netlist for spectre through simulation -> Netlist -> Create

The generated netlist is wrong:

M0 (A CKB B IVDD) pch3 l=Pl w=3u m=1 nf=1 sd=540.0n ad=1.44e-12 \
        as=1.44e-12 pd=6.96u ps=6.96u nrd=0.09 nrs=0.09 [COLOR="#FF0000"]sa=1/(1 / ((4.8e-07 + Pl/2)-07 +.4e-07 + Pl)*(1-1)/3.5 ) )-(0.5*Pl) \
         sb=1/(1 / ((4.8e-07 + Pl/2)-07 +.4e-07 + Pl)*(1-1)/3.5 ) )-(0.5*Pl) \[/COLOR]
         sca=0 scb=0 scc=0

Correct netlist should be:

    M0 (A CKB B IVDD) pch3 l=Pl w=3u m=1 nf=1 sd=540.0n ad=1.44e-12 \
        as=1.44e-12 pd=6.96u ps=6.96u nrd=0.09 nrs=0.09 [COLOR="#FF0000"]sa=1/(1 / ((4.8e-07 + Pl/2) + (5.4e-07 + Pl)*(1-1)/3.5 ) )-(0.5*Pl) \
         sb=1/(1 / ((4.8e-07 + Pl/2) + (5.4e-07 + Pl)*(1-1)/3.5 ) )-(0.5*Pl) \[/COLOR]
         sca=0 scb=0 scc=0

The OS is CentOS 7. I add "setenv CDS_AUTO_64BIT "EXCLUDE:si,si.exe"". Is there something wrong with Cadence's tool settings?


Thanks a lot!
