9.2i EDK SP1 Virtex-5 DCM Module 1.00.c - SIM_DEVICE not included on DCM_ADV
Description
Keywords: warning, NGDBuild:931, value of SIM_DEVICE
When I include the DCM Module 1.00.c in my design, the following warning appears:
"WARNING:NgdBuild:931 - The value of SIM_DEVICE on instance
'system/dcm_0/dcm_0/Using_DCM_ADV.DCM_ADV_INST' of type DCM_ADV has been changed from 'VIRTEX4' to 'VIRTEX5' to correct post-ngdbuild and timing simulation for this primitive. In order for functional simulation to be correct, the value of SIM_DEVICE should be changed in this same manner in the source netlist or constraint file.
Solution
The SIM_DEVICE was not added to the DCM_ADV instantiation. You can edit "dcm_module.vhd" to include this parameter; it is found in the following directory:$XILINX_EDK\hw\XilinxProcessorIPLib\pcores\dcm_module_v1_00_c\hdl\vhdl
On line 297, add the SIM_DEVICE parameter below the STARTUP_WAIT parameter:
STARTUP_WAIT => C_STARTUP_WAIT,
SIM_DEVICE => C_FAMILY
This issue has been fixed and scheduled to be released with EDK 10.1 available at:
