In Allegro, there is a case where a DRA package has been created, but the pin order is accidentally wrong and needs to be changed to the correct one. I believe this is a common problem for EDA engineers. At this time, the workload of repositioning pads is really heavy, and there is the possibility of error again. In fact, Allegro has provided a convenient way to modify the pin number, but many people don’t know. This article will introduce this shortcut.
1. Open a DRA package and open the pin number attribute under package geometry through the color dialog box, as shown in the following figure.
2. Click Edit – > text, as shown in the figure below.
3. Click the pad to be modified and change it to the correct pin number, as shown in the figure below.
4. The comparison between before and after modification is shown in the figure below.
