Good afternoon everybody,
I'm trying to find a way to add space between all of my cells when they are placed using Encounter. The process I'm working out of only has one metal layer, so I need to leave plenty of room for routing with M1 and poly bridges only. I have found Cell, Instance, and Module Padding in the documentation, but they do not seem to work reliably. Perhaps I am configuring it incorrectly? It seems that no matter how I tweak the settings, I still get 5-10% of the cells abutted together, with plenty of spare space in the floorplan for them to spread out. Any ideas?
can you post your specifyCellPad command?
I'm still in the early stages of the project. I'm still trying to get the "how do I?'s" out of the way, so this spacing is by no means scientific. The documentation said a wildcard (*) was valid, and since I need spacing on every cell, that seemed to be the way to go. Here's what I entered:
specifyCellPad * 10
Edit: <code></code> tags don't work on this board, apparently.
so you'll have seen that this command adds space on the right side of the cells. but if a cell is flipped on the y-axis, then the padding is on the left, and that's how you can add up with two cells abutted.
specifyCellPad * -left 10 -right 10
