Hello,

I'm trying to figure out what does "set_global_assignment -name USE_GENERATED_PHYSICAL_CONSTRAINTS OFF -section_id eda_blast_fpga" in the Quartus II Settings File (.qsf) mean and how to add a constraint.

Could you give me a quick example ?

Thanks,

Julien.

Hi,

"Blast FPGA" is the FPGA synthesis tool of MAGMA. It looks like that Altera plans to support the tool under the EDA Tool settings, because I did not find the tool in the tool list.

Look in the Quartus Help for "USE_GENERATED_PHYSICAL_CONSTRAINTS OFF". When the tool is really support you could set some features. Your setting means that all physical synthesis setting generated by "Blast FPGA" will be ignored by Quartus.

Kind regards
