Is there a limit to the size of the macro in the given area of wrapper. For the area of `2920 3520`, can I put a macro of size `2850 3450`. How much of a margin should be left on each side of any. <@U01634FSETZ> <@U016HSALFAN> <@U016EM8L91B>

<@U016Y9FMA2Y>: I agree with <@U016HU5HK8V> that you should probably use the whole user_project_wrapper as your project. However, to answer your question, I haven't tried that myself but I imagine if you use the same pin_order.cfg as the one used in the user_project_wrapper, then you should be fine as routing will be roughly a straight line from each pin to it's external connection.

<@U01634FSETZ> Then that is strange. I am getting this error `Error: Design congestion too high` which does not make sense since I used the same `pin.config` as that of the user wrapper and I was also expecting a straight line for route but it bombed
So I assumed I need to shrink my macro however according to you and <@U016HU5HK8V>  that's not the problem.
Under what circumstances do the flow give `congestion error`?

<@U016Y9FMA2Y>: then not all pins are aligned somehow (which happens pin_order.cfg doesn't create perfect alignment) and fastroute is unable to move around with wires so it needs more space. So, to answer you're question you get a congestion error when fastroute fails to route from point A to point B because it already create many wires in the way for other routes and it's not possible to reach from point A to point B (at least using the fastroute algorithm) for this given layout because it's become "congested" with wires. You can try 3 things:
1. what <@U016HU5HK8V> suggested above.
2. shrink your macro.
3. use user_project_wrapper as your macro and not user_project_example since you're already using almost all of the space.
This should be somewhat helpful <https://github.com/efabless/caravel/blob/develop/openlane/README.md#option-2>

or perhaps you're not centering your macro perfectly? did you check the placement def on klayout or something? Try using `manual_macro_placement` . Check this for more details about that <https://github.com/efabless/openlane/tree/develop/designs/manual_macro_placement_test>

I have already been using `manual_macro_placement` and I have also tried `set ::env(GLB_RT_ALLOW_CONGESTION) 1` ,unfortunately no luck.
I have been trying to integrate the SoC for the last 48 hours but I have hit a bottleneck.
Can any of you please help me with the integration process. We can have a quick 30 minute zoom session.

<@U016Y9FMA2Y>: Let me know when you'd like me to check the PDN issue we discussed.

<@U016HSALFAN> I am rerunning everything with the latest hashes. Would ping you as soon as I switch everything.
