How do I create GND plane on a 2 layered board. I am trying it on the solder side of the board. Will it interfere with the other nets on the solder side. Also I am getting isolated shape error and 0/1 out of date shape error. Please help.....
Hi, You have use VOID in Allegro 14.2 And Smooth in 15.2 to create copper pour before that you need to attache the shpe to required net and set the clearence parameters.
Hi~ do you using 15.x version? I think 15.x version dynamic shape problem. If you show the massage "out of data" but you are difficult of fine this point. so i teach you. If you are use the skill file. file name is "odd_shapes.il" usinge>> input the next sentence in allegro skill load "ood_shapes.il" than your allegro program loading... you are using command odd shape enter key
Once you have created your shape click on the button to the right of 'Assign net name' and pick the net (GND) off the list of net names. It will not interfere with the other nets on the solder side as it adheres to the constraint settings. If you are concened about isolated shapes, you can create voids around each isolated shape or connect them with a via and then a trace to a GND pin on the other side of the PCB. 0/1 out of date shapes is not an error. It simply says that 0 shapes are out of date. If you had 10 shapes and 3 were out of date, it would say: 3/10 out of date shapes.
Hi~ I think that Ground plane isolated. do you want merge isolat shape to Ground plane? If than you covert setup spacing rule. spacing rule change to small value. But problem of PCB produce than you give very small value. so limit 4mil space. If ground plane have many split shapes are a bad design. You would rather isolated shpaes delete.
