Why Arria® 10 SGMII Reference design in rocketboards.org doesn't work property? - Why Arria® 10 SGMII Reference design in rocketboards.org doesn't work property? Description Due to a problem in the Intel® Quartus® Prime Pro Edition software versions, you might see any errors with Arria® 10 SGMII Reference design on Arria® 10 SoC. Resolution To work around this problem in the Intel® Quartus® Prime Pro Edition software version 20.3 or later, follow the steps below 1) Open attached script ( run-cal-slack.tcl ) 2) Edit instance name for GMII to SGMII converter in the run_cal_slack.tcl as below set EMAC0 sgmii_1 set EMAC1 sgmii_2 set EMAC2 null set EMAC3 null The script can support up to 4 ports. A variable should be set ‘null’ if not needed. 3) Launch Timing Analyzer 4) Run updated script from a menu ( Script > Run Tcl Script ) 5) End of the workaround if the script returns 0. 6) Add two constraints below to top sdc in your project such as ghrd_timing.sdc. set_net_delay -min 1.2 -from [get_registers {*|altera_gts_clock_gate:u_pcs_tx_clk_gated|en_flp}] -to [get_pins -compatibility_mode {*|u_pcs_tx_clk_gated|clk_gated|combout}] set_net_delay -min 1.2 -from [get_registers {*|altera_gts_clock_gate:u_pcs_rx_clk_gated|en_flp}] -to [get_pins -compatibility_mode {*|u_pcs_rx_clk_gated|clk_gated|combout}] 7) Recompile your design. 8) Go to 3 if a timing is met. This problem is currently scheduled to be resolved in a future release of the Intel® Quartus® Prime Pro Edition software.
