Example projects

[phiph-s]

I've just wanted to ask if there are reference projects using our process using LibreLane to get the tapeout running.
I'm currently running into issues regarding the PDN (I get unconnected instances, "Check connectivity failed on VDD").
Thank you in advance.

PS: There is a typo in the challenges readme. I think it should be "MFRC522" instead of "NFRC522"

The Typo (MFRC) is fixed now.

Regarding your PDN issues and an example:
In #2 it is mentioned that there are a few issues left within librelane. @KrzysztofHerman wrote that this might be resolved by the end of January 2026. After librelane is fixed, the spm example should work? Did you try the spm example with the actual version of librelane?
@nhoeher did a testchip on this process node. Maybe he can provide information about his handling of the PDN.

Did you use the template provided by IHP?
This one:

In the readme, it says there is an example of a counter included:
