When I try to set an IOB SLEW attribute, the 2015.3 Vivado tools error out: [Synth 8-3438] module 'IOBUFE3' declared at '<path_to>/scripts/rt/data/unisim_comp.v:17551' does not have any parameter 'SLEW' used as named parameter override. ...
The param and result pointers must therefore point to structures only, and not to common types as int or float. In addition, there must be no pointers in the structures used. When processing arrays, these must be of fixed size and statically declared. For our first example function, here ...
"WARNING:Xst:1306 - Output <pin-name> is never assigned." Solution This warning is reported when ports are declared in the entity of your top-level VHDL design, but are not driven by any signals in your design. This can happen in the early stages of the design cycle if you have not...
