Can the grid/clips in the TritonRoute be exported?

Hello, I would like to know if the grid can be exported after the processing of the global router output and/or the TA step.
I'm planning on trying some other AI based approaches instead of Heuristics. And if I can export the grid or the clips it would be more helpful.
Any idea/help will be much appreciated!

Do you mean the gcell grid? There are messages
"GCELLGRID X {} DO {} STEP {} ;", "GCELLGRID Y {} DO {} STEP {} ;",
that will give you those values. They don't change during drt.

The post-processed guides are generated as output_guide.mod in ORFS (controlled by -output_guide). Other internal state of the router is not exported today.

Its the same guide format as the input guide file

Hello again,
I would like to get the access points to each pin in a net and I saw this on another discussion, however, when I tried it the coordinates didn't make sense.
For example when I try it on the nangate45 gcd, for the 000 net we have: _000_ ( _672_ D ) ( _504_ ZN ) + USE SIGNAL
and the components in the net are _672_ DFF_X2 + PLACED ( 107540 145600 ) N ; and _504_ OAI21_X1 + PLACED ( 107540 148400 ) FS ;
and this is the output of the code
net 000
( 46930 141260 ) layerNum 2 metal1
( 46930 141120 ) layerNum 2 metal1
( 46740 141260 ) layerNum 2 metal1
( 51490 146580 ) layerNum 2 metal1
( 51490 146860 ) layerNum 2 metal1
( 51490 147140 ) layerNum 2 metal1
( 51490 147420 ) layerNum 2 metal1
( 50730 147420 ) layerNum 2 metal1
( 51870 147420 ) layerNum 2 metal1
( 51870 147700 ) layerNum 2 metal1
( 51870 147980 ) layerNum 2 metal1
( 51110 147420 ) layerNum 2 metal1
So from what I see these coordinates can't be correct, any idea why is this happening?
