6758 - Diamond / Synplify Pro: Can the user ignore the "Unsupported property <parameter_name> found - ignoring" warnings of specific parameters when synthesizing using Synplify Pro?
Yes, these warnings are safe to ignore.
These warnings occur because, for any Verilog parameter or localparam, Synplify Pro will pass it with a value into EDIF as part of the original design info. Since such property cannot be recognized by back-engines, warnings are generated but can be ignored. By back-engines, we mean the back-end processes of Translate Design, where EDIF is translated to NGD.
As a sanity check, even though there are "Unsupported property... - ignoring" warnings related to specific parameters, the parameter values will still be reflected on the netlist. User can confirm this on the Technology View of Synplify Pro by right-clicking and checking the value of the specific parameter.
