Sir! I have an analog IP that I want to submit for MPW-two. Should I wait for the user_project_analog to be available or should I use caravel_user_project ?

If it requires high speed, high voltage, or very low noise, then wait for the analog project wrapper. If it can run < 20MHz and < 5.5V on the I/O, and you can tolerate a 150 ohm resistance between your analog signals in the pad, then you can use the existing caravel user project.
