How to use db command (not ge command - geIsPathReentrant) to check a path whether has a self-intersecting ?

Hi All,

I want to do a path check but not use geIsPathReentrant command , because when pcell has geIsPathReentrant ,

It will has error when stream out .

Thank you,

Hi Charley,

There is no "db" equivalent of this function. You'd need to contact customer support so that we can file an enhancement change request for this.

I've not seen any requests for this however - it's a fairly unusual thing to want to do within a pcell if you have control over the generation of the shapes in the first place - so why do you need this?

Regards,

Andrew.

Charley,

Detecting duplicate points in SKILL should be pretty easy - you can write your own function to do that, and then you can use that in your PCell.

Regards,

Andrew.
