I would like to import it in my SystemVerilog design. In Modelsim, I would simply compile the VHDL file with a special flag so it's compatible => vcom -mixedsvvh package.vhd. and then import it in my SystemVerilog file with => import package::*; And everything works fine during the simulation. VHDL Math Tricks of the Trade VHDL is a strongly typed language. Success in VHDL depends on understanding the types and overloaded operators provided by the standard and numeric packages. The paper gives a short tutorial on: •VHDL Types & Packages •Strong Typing Rules •Converting between Std_logic_vector, unsigned & signed •Ambiguous hwt.serializer.vhdl package¶.

A Package is a VHDL file, which can be used to contain user defined data types,constants, functions, procedures etc. Coverage of VHDL packages will be light; the block structural statements and The std_logic_1164 package defines a multi–valued logic system which will be IEEE std_logic_1164 package. ▫ Which standard VHDL operators can be applied to std_logic and std_logic_vector?

I am trying to use the floating point package that comes with VHDL2008 to have a custom floating point type ; I need half-precision (16 bits) floating numbers. Being unexperienced with VHDL, I folowed the "Floating point package user guide" found here. On page 7, it describes how to use "float_pkg" with custom bit sizes.

It uses VHDL-2008 back- compatible libraries (by David Bishop) that are included in this distribution for the sake of completeness. In the VHDL code, the full adder is implemented in line 24 on the registered input. Pay attention that before performing the addition operation you must extend the number of bit of the input operand. This is implemented using the standard “ resize ” function provided in the “ numeric_std ” package … 2016-06-27 In the VHDL language, the libraries STD and WORK are implicitly declared in the source code.

Each package comprises a "declaration section", in which the available (i.e. exportable) subprograms, constants, and types are declared, and a "package body", in no, it is not, because library clauses are evaluated statically, what you would need is something like dynamic binding which is not possible in vhdl.
