Description

This is a set of common types defining unconstrained arrays of arrays in VHDL-2008 syntax. This provides a common set of types and conversion functions that can be used to interoperate between different library components that need to make use of fully unconstrained types.

Types

common.sulv_array

Array of std_ulogic_vector.

common.slv_array

Array of std_logic_vector.

common.unsigned_array

Array of unsigned.

common.signed_array

Array of signed.
