Thanks @Mitch Bailey. That was the issue alright. Re-running now places the pins on the sides I want. However, as shown, the outputs "out<3:0>" are spaced ~100um between each other. How do I specify to place them close to each other, say 1 M3 pitch apart? I see also the pwn/gnd straps are added. Suppose I wanted to increase this strapping. How do I go about doing that? Thanks
