DDR IP on stratix3
Hi, my project uses stratx3 insides ddr3 controller w/UniPHY,
on Fitter lots of 174068 and 174058 errors are appared.
Error (174052): I/O "mem_dq[0]" has dynamic termination control connected, but does not use parallel termination
that repeats for
mem_dq[0] ~ mem_dq[31]
mem_dqs[0] ~ mem_dqs[3]
mem_dqs_n[0] ~ mem_dqs[3]
Error (174068): Output buffer atom "ddr3_ip:U_ddr3_ip|ddr3_ip_0002:ddr3_ip_inst|ddr3_ip_p0:p0|ddr3_ip_p0_memphy:umemphy|ddr3_ip_p0_new_io_pads:uio_pads|ddr3_ip_p0_altdqdqs:dq_ddio[2].ubidir_dq_dqs|altdq_dqs2_ddio_3reg_stratixiii:altdq_dqs2_inst|obuf_os_0" has port "SERIESTERMINATIONCONTROL[0]" connected, but does not use calibrated on-chip termination
this repeats for

approx. 1100 errors in Fitter process.
Is there any way to solve this?
IIRC, you had to run a Tcl script to create all the I/O assignments needed to work with the IP. Did you run that script?
