take pin connection from reference design?

hello, i'm jackeroo in this area. Can anybody help me, how can i take the pin connection from reference design.

i have a reference design for my eval-board. now i create a new porject in QuartusII, i modify the reference SOPC data(only add a CAN ip-core in SOPC) and save it in my new project. now i want to have the same pin connection like reference design, because the pin connetion fit the eval-board. how can i take the pin connection from reference design?

i tried to import the reference design '.qsf' data in QuartusII under "assingments"->"import assingments". But the I/O name doesn't agree to the neu project.

thanks in advance

Niu

    Pin assignments are available:

    1 - In the assignment editor

    2 - In the QSF file

    What I would do is:

    1 - In the reference project, open the pin planner.

    2 - Click File->Export

    3 - Change the "Save as type" to TCL.

    4 - Export the pin assignments to a TCL file.

    Now you have a TCL file with the pin assignments. You can edit it or whatever. Then just run it in your new project "Tools->TCL Scripts".

    thanks jake. aber i was really confused.

    i did what you told me. after run the Tcl script, i recompile it in Quartus II. then i open the .pin data, the pin connection look totally different.

    the reference design has own's I/O pin name. the I/O name in my project is different in reference design. Is that the possible reason? how can i do?

    thanks!:)

    yes, you'll want to reflect the names in the reference design in your project if you want to copy the pin assignments verbatim.
