save ahdl variable option

Hi,

In the save option of assembler, basic page, there is one option: select AHDL variable (saveahdlvars). 

Q1, if "selected" is chosen, how to define those selected variable in assembler?

Q2, there two verilogA models, A and B. I wish to save variables only in A, but NOT in B. How to define?

My spectre version is 21.1.0.664, isr 16. 

Thanks for your attention!
