WebIt effectively becomes an unused hierarchical pin, but RC, by default, will tie it off so it is not undriven. What you need to do, to further investigate, is run "check_design -constant" and look at any constant hierarchical pins have a fanout greater than 0. A fanout of 0 means that it is an unused hier pin, which is not an issue. For example: WebI have included virtual I/O block in block design. vio_0 - only has output. vio_1 - has only inputs vio_2 - has only input. Both vio_0 and vio2 on out of context synthesis give following warning. 37 x [Synth 8-3295] tying undriven pin inst:sl_iport0 [36] to constant 0 37 x [Synth 8-3295] tying undriven pin inst:sl_iport0 [36] to constant 0 I ...
