Hyper-Retiming, How to disable it in the .qsf?

Hello Alex,


Without your design, it will be difficult for me to help you. Is it possible to share through e-mail?


I have checked with the internal team, they have confirmed that your target OPN 1SX280HU2F50E1VG should work with the ASIC_PROTOTYPING_FEATURES qsf.

Can you share the compilation time of before and after adding the set_global_assignment -name ASIC_PROTOTYPING_FEATURES ON qsf setting?

Also, does the compilation report show any reports for retime stage?


Regards,

Nurina

    Hi Nurina,

    I'm running 2 Quartus jobs with the option ON and OFF for you to compare.

    I can already see in the stratix10_fpga_a_mix.flow.rpt that the option is picked:

    +----------------------------------------------------------------------
; Flow Non-Default Global Settings                                     
+---------------------------------------+------------+-----------------
; Assignment Name                       ; Value      ; Default Value   
+---------------------------------------+------------+-----------------
; ALLOW_REGISTER_RETIMING               ; Off        ; On              
; ASIC_PROTOTYPING_FEATURES             ; On         ; Off             
; ASIC_PROTOTYPING_LATCH_SUPPORT        ; On         ; Off             
; ASIC_PROTOTYPING_READBACK_WRITEBACK   ; On         ; Off

    I will send by email the reports and .qsf
