Multiprocessor using DE2-70 board

[Altera_Forum]

Hello all, 

I want to design multiprocessor project using DE2-70(EP2C70F896C6N). I am getting pin assignment error as : Quartus II --------------------------- I/O Assignment Analysis was NOT successful (50

highlited above"error: can't fit design in device" ? I have tried a lot with pin assignments .by importing .qsf file .But still getting the same error.

It looks like you are compiling a design made for a 2c35 Cyclone into a 2c70. Are you sure the design you are compiling is for the DE2-70 and not the regular DE2? I don't know if the two boards are pin-to-pin compatible.

Thank you I got the solution. 

I have compiled it correctly bou getting time limited sof file. can you please tell me what is time limited sof file. Is it necessary to have a paid license for the software for device prograaming(i.e. Generating valid .sof file)? oR WB EDITION perform properly?   also when I program using time limited .sof file I am getting error message in Nios II IDE as processor not responding whan running the Hello world.c program. Can you plaese giude me?
