is there any documentation for dcmatch analysis?

I cannot make dcmatch analysis works in my setup.
I do not know if it is because the setup, the model, or something else.
is there any documentation for dcmatch analysis that I can use as a reference?

From here p426, I am informed that dcmatch requires some specific bsim parameters.
But I cannot find them in the model files. I checked directly in the model directory from the 2 different foundries for 3 different PDKs.
From Cadence simulation, inside model directory, I can find those parameters but the value is 0 for all of them.

Just for comparison, I follow mismatch RAK, but somehow no model directory in the simulation results.
So, I cannot compare, confirm, and narrow down the source of the issue.

EDIT:
From here, I know the meaning of some parameters.
They are AVT and Abeta, basically, and I know the values for my PDK.
If there is a way to add these manually without modifying the PDK, I would like to know as well.
I am still expecting the dcmatch documentation, though.

The Spectre installation directory contains a dcmatch tutorial.
Go to the directory $SPECTRE_HOME/tools/spectre/examples/DCMatch to access the tutorial.

Kind regards

Change the method on the dcmatch analysis to "statistics" rather than "standard". Then it will use the Monte Carlo statistical information (assuming you have this) rather than requiring special model parameters. That's nearly always the right way to solve this rather than requiring you to modify model files.

I tried with "statistics" method and it gives some number which I think makes sense.
But I sitll wonder if there is a way to add AVT and ABeta values manually and savely to the PDK.

You could probably do it by using alter statements in a file with mod=XXX param=YYY value=ZZZ to modify the models. I've never tried doing this though with dcmatch parameters.
