Forum Post: RE: Versal AD9082 FMCA-EBZ M4 L8 JESD204C design - cont. (SYSREF alignment error)
Hi iulia , 1. The timing_constr.xdc file I use (uploaded above) is practically identical to the default file here: https://github.com/analogdevic....esinc/hdl/blob/main/ Do you think this is correct? 2. Reading your reply, I recalled an issue I had during the VPK180-to-VPK120 migration. When I built the VPK180 design, I specified M4 L8 JESD204C. However, in the system_top.v file, the parameters written are: module system_top #( parameter TX_JESD_L = 4, parameter TX_NUM_LINKS = 1, parameter RX_JESD_L = 4, parameter RX_NUM_LINKS = 1, parameter JESD_MODE = "8B10B", parameter GENERATE_LINK_CLK = 1 Apparently, this isn’t a problem, since the parameters are bound to the correct values by the build scripts. However, when building the design for VPK120 using Vivado, I had to explicitly write the correct values, in order to avoid an error: module system_top #( parameter TX_JESD_L = 8, parameter TX_NUM_LINKS = 1, parameter RX_JESD_L = 8, parameter RX_NUM_LINKS = 1, parameter JESD_MODE = "64B66B", parameter GENERATE_LINK_CLK = 1 Does this make sense? Best of regards, EW1
