More mux woes

See original GitHub issue

I’m not really sure what’s going on, but I found an alternative, so I’m posting this as an issue to be looked at later.

When I mux a DspReal and zero (where DspReal is a bundle with a UInt node), I get:

[info]   firrtl.passes.PassExceptions: firrtl.passes.CheckChirrtl$UndeclaredReferenceException:  @[Chisel_WFTA.scala 391:17]: [module WFTA] Reference C72 is not declared.

[info] firrtl.passes.CheckChirrtl$UndeclaredReferenceException:  @[Chisel_WFTA.scala 405:17]: [module WFTA] Reference scalarZero is not declared.

The DspReal was type parameterized. When I used FixedPoint instead, it worked… not sure why Mux is so grumpy…

This issue has been a zombie for a while, if it’s still an issue, can you re-open this with an update?

I’ll have to look at it later, but I think it was Lit Bundle issue… I think a significant % of my problems with tapeout stemmed from the fact that I couldn’t construct a Bundle of Lits and it wouldn’t explicitly error…
