Hi,

1) This set_false_path -> set_false_path -from [get_pins -no_case -compatibility_mode *SPIPhy_altera_avalon_st_idle_inserter|received_esc*|*] -to [get_pins -no_case -compatibility_mode *|rdshiftreg*|*] in MISO block is wrong.

This is fixed in 19.1std b659 onwards to -> set_false_path -from [get_pins *] -to [get_pins -no_case -compatibility_mode *|rdshiftreg*|*]

Can you please either regenerate the RTL or replace the SDC content?

2) This set false path -> set_false_path -from [get_pins -no_case -compatibility_mode *|stsourcedata*|*] -to [get_registers *] is in MOSI block.

I noticed from the Technology map viewer that MOSI block doesn't exist (synthesize away). Did you not connect up MOSI interface? If this is expected then this set_false_path can be ignored.

Thanks.
