Help on pcell code.

hi all,

I created pcell using the code specified in rod objects in my install directory. To achieve it entered following code in my CIW and created pcells. My version is 6.1.

setSkillPath(cons(prependInstallPath("samples/ROD/rodPcells")
getSkillPath()))
load("install/spcLoadInstall.il")
spcInstall()

Pcell working fine without any errors. Then I created a schematic with all options(fingers, multipliers....) and get all devices in layout by doing Gen From source. When I overlap two pcells then it automatically adjusts side by side by merging drains and taps. Now I need control of that adjustments because I didn't get minspacing at drain/source merging.

Thank you.

Hi,
   My LVS is not running perfectly. Actually in this technology we have only caliber rulefiles. So I wrote layer derivations, definitions, extract devices in extract.rul file. I got following warnings in LVS.wrn file. Please Solve this if you have Idea about verification codes.
This LVS is for INVERTER

   Here spcnmos,spcpmos are pcells. In extract.rule file I defined layer defitions and derivations. For extraction of MOS is like this.
   npod      = geomAnd( nimp diff )

    nameParameter( w_PMOS "w" )
    nameParameter( w_PMOS "effW" ); REQUIRED FOR SPECTRE
In compare rule:
I didn't edit parallelmerge, seriesmerge, compare checkings. After these I wrote Like this
schematic(
    genericDevice( emptySubckt )

    mosDevice( "spcpmos" ( "D" "G" "S" "Sub" ) "w" "l" )
    mosDevice( "spcnmos" ( "D" "G" "S" "Sub" ) "w" "l" )

    )

layout(
    mosDevice( "spcpmos" ( "D" "G" "S" "Sub" ) "w" "l" )
    mosDevice( "spcnmos" ( "D" "G" "S" "Sub" ) "w" "l" )

mergeSeries( "spcpmos" noMerge )
mergeSeries( "spcnmos" noMerge )

compareParameter( "spcpmos" compareMOS )
compareParameter( "spcnmos" compareMOS )

) ;end avCompareRules

I got 4 nets and 4 devices errors for INVERTER. And parameters errors are not showing in errors report but in layout parameter are diferent from schematic.
