A causa di un problema con il file SDC PCIe* Hard IP, quando si utilizza Intel® Arria® 10 PCIe* Hard IP Gen3, saranno riportati i seguenti percorsi di temporizzazione:
da *altpcie_a10_hip_pipen1b:altpcie_a10_hip_pipen1b|wys~ch3_pcs_chnl_hip_clk_out[0].reg ad altri elementi all'interno dell'HARD IP.
Questi percorsi possono essere ignorati in modo sicuro.
Per risolvere questo problema, questi percorsi possono essere ignorati utilizzando le seguenti assegnazioni false path sdc impostate:
set_false_path -da {*|altpcie_a10_hip_pipen1b:altpcie_a10_hip_pipen1b|wys~ch3_pcs_chnl_hip_clk_out[0].reg} -a {*:p hy_g3x8|twentynm_xcvr_native:g_xcvr_native_insts[*].twentynm_xcvr_native_inst|twentynm_xcvr_native_rev_20nm5:twentynm_xcvr_native_inst|twentynm_pcs_rev_20nm5:inst_twentynm_pcs|gen_twentynm_hssi_common_pld_pcs_interface.inst_twentynm_hssi_common_pld_pcs_interface~pld_rate_reg.reg}
