I'm using the UniPHY for a DDR2 application in a Stratix IV. When I simulate the example project, I get a bunch of warnings along the lines of:
Warning-[PCWM-W] Port connection width mismatch ../rtl/uphy_altdqdqs.sv, 787 " stratixiv_delay_chain genblk6.genblk3.oct_delay_2( .datain (genblk6.genblk3.delayed_os_oct_1), .delayctrlin (octdelaysetting2), .dataout (genblk6.delayed_os_oct));" The following 3-bit expression is connected to 4-bit port "delayctrlin" of module "stratixiv_delay_chain", instance "genblk6.genblk3.oct_delay_2". Expression: octdelaysetting2 In possibly related news, the simulation fails in calibration. Has anyone else seen these warnings?
