Hierarchical design default pin placements

algoldst
algoldst over 6 years ago

In Capture, I have created a hierarchical design with 8 input pins and 255 output pins. The outputs, in particular, are labelled

SigOut0, PwrOut0,

SigOut1, PwrOut1, 

SigOut2, PwrOut2,

...

SigOut127, PwrOut127.

For some reason, the output pins aren't ordered like this on the schematic when I place a block. I suspect it orders them based on time created, and maybe because I used F4 to duplicate, some of the ports were created simultaneously and are therefore out of order. 

How can I set the default ordering of pin placement? At present, I have to drag around 255 pins to place them in order when I draw the block (at least, the first time), and if I want to preserve this, I have to copy-paste the block because placing it manually (via "Place Hierarchical Block") has the same problem every time. 

I highlighted the pins that are properly ordered in green, and red for those that are out of order.

    You cannot affect the default order of H-Pins assigned to a H-Block. In this specific case, since the signals follow a numerical sequence, you could use a Bus SigOut[0-127] / PwrOut[0-127] (or SigOut[127-0] / PwrOut[127-0]) and then just route the two buses around and reduce the H-Pins to 2.
