i wanted to create a tristate output and used a
<
ikskuh>
assign output = condition ? value : 1'bZ;
<
ikskuh>
but then the Warning: Yosys has only limited support for tri-state logic at the moment.
<
ikskuh>
appeared and it seems like it's not doing any tristating
<
ikskuh>
i guess this is a known problem, can someone point me into the right direction?

IIRC tristate are only supported on top level signals/IOBs
<
ikskuh>
yeah they are on my top, "inout output"
<
ikskuh>
no other tristate signals in the design
<
jevinskie[m]>
Hmm, I’m all out of ideas then :)
<
ikskuh>
still, thanks :)
<

let's check if it works if i don't use a $_TBUF_
