object LowerTypes extends Transform

Removes all aggregate types from a firrtl.ir.Circuit

Example:
  1. wire foo : { a : UInt<32>, b : UInt<16> }

    lowers to

    wire foo_a : UInt<32>
    wire foo_b : UInt<16>
Note

Assumes firrtl.ir.Connects and firrtl.ir.IsInvalids only operate on firrtl.ir.Expressions of ground type

,

Assumes firrtl.ir.SubAccesses have been removed
