I recompiled AN881 for S10 MX 16G HBM2 p/n 1SM21CHU1F53E1VG on Q19.2 Pro.
When I did 1st read of HBM2, I saw both hbmc_axi_0_0_rlast and hbmc_axi_0_0_rvalid were aligned to hbmc_axi_0_1_rlast and hbmc_axi_0_1_rvalid though the c output was wrong 0xFFFFFFFF (stp file: stp1_read_addr0_getffffffff.7z). When did 2nd or more reads, hbmc_axi_0_0 misaligned hbmc_axi_0_1, rdata were not aligned, too (stp file: stp1_read_addr100_getffffffff.7z). The c output was still wrong.
I think the reading data and signals of HBM2 should always align since these are combinational circuits. Please confirm this. Thanks.
Thank you for joining this Intel Community.
Please allow me sometime to look into your issue. I shall come back to you with findings.
Thank you for your patience.
