how to add lvsIgnore property to a cell made by myself.

First of all, please read the forum guidelines. These tell you not to post the same question in more than one forum - this question  you posted twice in the mixed signal forum and once in this forum. I attempted to merge the two in the mixed-signal forum but this seems to have just resulted in one of the duplicates being deleted.

Isn't this just CIW->Tools->CDF->Edit CDF?

In fact I try this ,but when I export cdl, this cell still there.

I use" Name: lvsIgnore  Prompt:  lvsIgnore type:boolean  Default Value: true"

Thanks.

I just tried this, and it worked fine. A couple of questions:

1. Did you select "Base" as the CDF Layer when editing the CDF? You need to do that otherwise the change won't get saved.
2. Are you using the Analog netlisting mode? (what does the SKILL function cdsGetNetlistMode() return?)

OK, I didn't realise you were doing it on a hierarchical component rather than a leaf cell. If you do that, it omits the instance line, but still netlists the underlying schematic as a .subckt - it just wouldn't be referenced.

If you don't want it to appear at all, what I'd suggest is going to the library manager, and copying the symbol view for the block you wish to ignore to be called "auCdl", and then open the auCdl view for edit, and add a cellView property (Edit->Properties->CellView in the symbol editor) and then adding a boolean property called "lvsIgnore" with value t.

Then the instance and the definition won't appear.

Andrew.
