180nm Calibre PEX error，especially Calview setup error

Hello everyone,
I'm using Charter_018BCD PDK. I made a DAC and have performed DRC, LVS successfully. But when I performed PEX whose output is CalView, I ran into some problems. The error show as follows:
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v nmoscap_1p8 ivpcell). It will remain unconnected."
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v pmoscap_1p8 ivpcell). It will remain unconnected."
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v nmoscap_6p0 ivpcell). It will remain unconnected."
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v nmoscap_6p0_dw ivpcell). It will remain unconnected."
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v pmoscap_6p0 ivpcell). It will remain unconnected."
"error: Could not find pin mapping for terminal "SUB" of cell (chart018ull_hv30v pmoscap_6p0_dw ivpcell). It will remain unconnected."

I don't understand what these errors mean, and what should I do to eliminate these errors.In my circut, there is no pin "SUB". I will attach some screenshots of errors and warnings.

Dose anyone kown how to solve these problems?
Thanks!

BTW, the reason this was marked as spam was because it has lots of repeated text in it - that triggers the spam detection.

I moved it out of moderation because it's not spam, but that said, posting here is not the best place. Calibre is not a Cadence tool. It's from Mentor (now Siemens) and so you would be far better off asking this question to either Siemens support or in a forum on the Mentor/Siemens site (if there is one - I've not checked recently).

Regards,

Andrew
