Reverse operation of dbProduceMemName

RK56

Hi,

Is there a function that can create short form bus expression from an expanded expression. Something like a reverse operation of dbProduceMemName

For example,

"vdd, nr3<1>,nr3<2>,nr3<3>,nr3<4>, vss" should be returned as "vdd, nr3<1:4>, vss"

"A, A, B, C" should be returned as "<*2>A, B, C"

Thanks

    Hi Ramakrishnan,

    Here's some code I wrote (in 2007) to do this. It does a reasonable job - but it won't completely collapse things. In your case, it works though (provided you don't have spaces in the original names, because dbProduceMemName doesn't handle that):

    bundle="vdd,nr3<1>,nr3<2>,nr3<3>,nr3<4>,vss"
    collapsedParts=abCollapseAdjacentSignals(dbProduceMemName(bundle))
    collapsed=buildString(collapsedParts ",")

    produces: "vdd,nr3<1:4>,vss"

    bundle2="A,A,B,C"
    collapsedParts2=abCollapseAdjacentSignals(dbProduceMemName(bundle2))
    collapsed2=buildString(collapsedParts2 ",")

    produces:  "<*2>A,B,C"

    Andrew.
