Routing error

[rachary00]

I get the following error:

I am using a simple custom circuit and the PDK files are all the mock files provided in the GitHub. I am not sure what this error is exactly. Please help!

Looked at the log. It might because the router cannot find a access point for a pin. We first find the overlapping points of a pin shape and the routing grid.

@baloneymath Do you know anything about it?

[baloneymath]

It should be caused by some pins that were not on-grid and thus no valid access point exists. @rachary00 could you check if the pins in your circuit are correct?

[rachary00]

yes the pins in schematic file look fine, is there any place else that you want me to check them?

[baloneymath]

@rachary00 could you check if the layout after placement (before running routing) is correct? This problem seems that the layers are not initialized correctly.

It looks correct, not sure what to check exactly, but all the transistor cells are in the right location
