What are the symptoms that the "auto adjustment" function is not activated for some transistors?

Daeho

Hello. Nice to meet you. I'm inquiring because there are many things I don't know when It's my first time setting it up
Auto Adjustment is not working for some Trasistor currently using GF40nm process.
The symptom is that when Auto Adjustment is the same option,
LV TR and RV TR become S/D junctions merged, and MV TR is not S/D junction merged.
Is there a way for the user to solve this problem? i want MV TR also S/D junction merged.

Thank you every one

have a nice day

    I'm not that familiar with the GF40nm technology that you're referring to - maybe somebody else will know. You might want to elaborate on what you mean by "Auto Adjustment" or even what "LV TR", "RV TR" or "MV TR" mean? Are these options on the transistor properties form?

    Thank you for your answer. I'm sorry for the weak explanation.
    To briefly explain, the tool currently in use is Virtuoso 6.1.8 Ver, the LVTR is the Low Voltage Trasistor(voltage gap 1.2V), the RVTR is the Regular Voltage Trasistor(voltage gap 1.8V), the MVTR is the Middle Voltage Trasistor(voltage gap 8V), and the Auto Adjustment option is in the generation category of Layout XL options

    Thank you
    have a nice day
