.qsf file problem

Greetings

I have code that was compiled in Quartus 10.1 and am trying to open it in 9.1. I keep getting an error with these lines. If I delete them my clocks break but I cannot open the project with them. is there a work around?

set_global_assignment -name OUTPUT_IO_TIMING_NEAR_END_VMEAS "HALF VCCIO" -rise

set_global_assignment -name OUTPUT_IO_TIMING_NEAR_END_VMEAS "HALF VCCIO" -fall

set_global_assignment -name OUTPUT_IO_TIMING_FAR_END_VMEAS "HALF SIGNAL SWING" -rise

set_global_assignment -name OUTPUT_IO_TIMING_FAR_END_VMEAS "HALF SIGNAL SWING" -fall

Any suggestions?

Thanks

    I tried that and the design wouldn't compile because the clocks were missing parameters.

    Something must be wrong with your observation. Quartus V9.1 doesn't use the said parameters. They are not specifying clocks. What's the full compiler error message?
