    Hi the brick,

    Thanks for your reply.

    But my question was different.For example,there are many assignments like Location,PCI/O,current strength,slew rate,virtual pin,I/O standard..etc)

    I know the usage of "Location" which is used to assign exact pin location.even i did use "current strength with 12ma"for DDRSDRAM pins(it is suggested in kit user guide only) in my design.Like that ,i need some resource/links to learn about all assignment names.

    Thanks & Regards

    well, in the assignments editor you have the information window which gives some basic information (surprise) about every assignment.

    I believe that the most used for synthesis are

    set pin location

    current strength

    weak pull up

    and you might find this one also useful:

    set virtual pin
