For example, the shape in PACKAGE KEEPOUT or ROUTE KEEPOUT,how to create a void manually like doing that in an etch shape?
You cannot have voids in non etch shapes. Shapes where you would require a hollow i.e. doughnut, such as route keepouts, must be made with one shape being a ‘C’ shape and another shape being added to close the opening.KP
Or you can use a single shape with a small gap.
Yes, I always do it like this: Use the function: Shape Edit Boundary, Cut a big void and remain a small gap, it seems a "C" shape.But I think it is a stupid solution.Does anyboy have other effective solution?Thanks.
I would agree that there should be a better solution. Would be a good idea to raise a CRC with Cadence. This is an improvement which would be very welome. You never know it may already be included in a forthcoming release.
I always use the Ohio Harmony tool to acomplish this. I create my void in a etch shape (must be static shape) then change this voided etch to the desired layer in Allegro.Not helpful if you don't have Harmony...sorryI think this capabilty would be a good feature to add to the Allegro tool.
