Max10 On-Chip-Flash/Dual Configuration Unconstrained Clocks

Hi, 

 

I'm using altera_dual_boot and altera_onchip_flash in a MAX10M08DAF256C8G with Quartus Prime Lite 15.1.0. 

In TimeQuest I get the followed messages: 

 

Node: ...|altera_onchip_flash_onchip_flash|altera_onchip_flash_avmm_data_controller:avmm_data_controller|read_state.READ_STATE_SETUP was determined to be a clock but was found without an associated clock assignment. 

Register ...|altera_onchip_flash_onchip_flash|altera_onchip_flash_block:altera_onchip_flash_block|ufm_block~XE_YE_TO_SE_FF is being clocked by ...|altera_onchip_flash:onchip_flash|altera_onchip_flash_avmm_data_controller:avmm_data_controller|read_state.READ_STATE_SETUP 

 

Node: ...|altera_dual_boot:dual_boot|alt_dual_boot_avmm:alt_dual_boot_avmm_comp|alt_dual_boot:alt_dual_boot|ru_clk was determined to be a clock but was found without an associated clock assignment. 

Register ...|altera_dual_boot:dual_boot|alt_dual_boot_avmm:alt_dual_boot_avmm_comp|alt_dual_boot:alt_dual_boot|ru_regout is being clocked by ...|altera_dual_boot:dual_boot|alt_dual_boot_avmm:alt_dual_boot_avmm_comp|alt_dual_boot:alt_dual_boot|ru_clk 

 

Are there any solutions to constrain the signals and avoid this messages? 

 

Thanks and best regards

Is your .sdc file simply out of date? Have you updated your design but not reflected the changes in the timing constraints file? 

 

Cheers,
