missing dollarEqualParams in capacitor subckt in auCdl netlist

Hello,

I want to make these lines in auCdl netlist.

.SUBCKT umim PLUS MINUS
CC0 PLUS MINUS 1.5E-4*cw*cl $[CA] $L=cl $W=cw
.ENDS
XC1 out gnd! /umim cl=20 cw=20

But auCdl netlist gives
.SUBCKT umim PLUS MINUS
CC0 PLUS MINUS (cw)*(cl) $[CA]
.ENDS
XC1 out gnd! / umim cl=20 cw=20

From Virtuoso Analog Design Environment User Guide Product Version 5.1.41, p.629,  only C or area or (L&W) will be outputted in the netlist. How could I make auCdl netlist shown above lines?

Also dollarEqualParams cannot be printed even after I type in CDF as shown below.But from manual, $L=cl $W=cw should be printed when I type into the field of dollarEqualParams, why this cannot happen?

Thanks in advance for your help

The umim CDF is

        error( "Could not get cell %s." CELL )
    )

        cdfDeleteCDF( cdfId )
