I have to use the vrtuoso VXL seems to be a bit of a problem.
Use the module generation in schematicXL, I make a consistant. and Made at the schematic that have come from the layout view.
Okay until here. Erase everything that is on the layout view.
then, strange pcell pattern is shown when i click the "update components and nets" button in layoutXL view.
schematic symbol and module in layout have different properties.
What is the problem and how to solve this?
I don't know what a "consistant" is, or what "Made at the schematic that have come from the layout view" means.
I do understand that English may not be your first language, but I'm not sure anyone would be able to understand what you're asking or what the problem is. Maybe some pictures would help? (Use the Options tab when replying to upload pictures).
I would guess that you are talking about constraints and a modgen constraint in particular? If this is the case then you can update the layout constraints using the 6th icon that has a yellow arrow in it: "Update all layout constraints from schematic", in case somehow you have modified the modgen constraint in the the schematic constraint manager but not regenerated the layout since. If you use Generate All From Source (or "Connectivity -> Generate -> All from Source") then the layout should pull the latest schematic components and constraints.
I'm guessing here, so if this does not help, as Andrew requested, please upload any image(s) that might help explain the issue, along with a more detailed description.
