Data types

Introduction

The language provides 5 base types, and 2 composite types that can be used.

• Base types: Bool , Bits , UInt for unsigned integers, SInt for signed integers and Enum.

• Composite types: Bundle and Vec.

In addition to the base types, Spinal has support under development for:

• Fixed-point numbers (partial support)

• Floating-point numbers (experimental support)

Finally, a special type is available for checking equality between a BitVector and a bits constant that contains holes (don’t care values). An example is shown below:

val myBits  = Bits(8 bits)
val itMatch = myBits === M"00--10--" // - don't care value
