I am working on a 90 position burn-in PCB. That is 90 identical circuits to be layout in a 9 rows by 10 columns on a single burn-in PCB. Is there a way to hasten my placement to the board? I am using cadence allegro v16.3 for layout. Each block is being represented by a hierarchy on the cadence concept v16.3. These means that my components ref des appears like C1_1,R1_1, R2_1 . . . for circuit block 1, C1_2, R1_2, R2_2 . . . for circuit block 2. I am currently using placement edit mode for replication of each placement and routes per block. My method still requires me to repeat the process ninety times for this project for all circuits to be placed. Does anyone here knows a better approach?
