-- Maintainer: Jim Lewis email: [email protected]
-- Contributor(s):
-- Jim Lewis SynthWorks
-- Matthias Alles Creonic. Inspired GetMinBinVal, GetMinPoint, GetCov
-- Jerry Kaczynski Aldec. Inspired GetBin function
-- Sebastian Dunst Inspired GetBinName function
-- ... Aldec Worked on VendorCov functional coverage interface
--
-- Package Defines
-- Functional coverage modeling utilities and data structure
--
-- Developed by/for:
-- SynthWorks Design Inc.
-- VHDL Training Classes
-- 11898 SW 128th Ave. Tigard, Or 97223
-- http://www.SynthWorks.com
--
-- Revision History: For more details, see CoveragePkg_release_notes.pdf
-- Date Version Description
-- 06/2010: 0.1 Initial revision
-- 09/2010 Release in SynthWorks' VHDL Testbenches and Verification classes
-- 02/2011: 1.0 Changed CoverBinType to facilitage long term support of cross coverage
-- 02/2011: 1.1 Added GetMinCov, GetMaxCov, CountCovHoles, GetCovHole
-- 04/2011: 2.0 Added protected type based data structure: CovPType
-- 06/2011: 2.1 Removed signal based coverage modeling
-- 07/2011: 2.2 Added randomization with coverage goals (AtLeast), weight, and percentage thresholds
-- 11/2011: 2.2a Changed constants ALL_RANGE, ZERO_BIN, and ONE_BIN to have a 1 index
-- 12/2011: 2.2b Fixed minor inconsistencies on interface declarations.
-- 01/2012: 2.3 Added Function GetBin from Jerry K. Made write for RangeArrayType visible
-- 01/2012: 2.4 Added Merging of bins
-- 04/2013: 2013.04 Thresholding, CovTarget, Merging off by default,
-- 5/2013 2013.05 Release with updated RandomPkg. Minimal changes.
-- 1/2014 2014.01 Merging of Cov Models, LastIndex
-- 7/2014 2014.07 Bin Naming (for requirements tracking), WriteBin with Pass/Fail, GenBin[integer_vector]
-- 12/2014 2014.07a Fix memory leak in deallocate. Removed initialied pointers which can lead to leaks.
-- 01/2015 2015.01 Use AlertLogPkg to count assertions and filter log messages
-- 06/2015 2015.06 AddCross[CovMatrix?Type], Mirroring for WriteBin
-- 01/2016 2016.01 Fixes for pure functions. Added bounds checking on ICover
-- 03/2016 2016.03 Added GetBinName(Index) to retrieve a bin's name
-- 11/2016 2016.11 Added VendorCovApiPkg and calls to bind it in.
-- 05/2017 2017.05 Updated WriteBin name printing
-- ClearCov (deprecates SetCovZero)
-- 04/2018 2018.04 Updated PercentCov calculation so AtLeast of <= 0 is correct
-- String' Fix for GHDL
-- Removed Deprecated procedure Increment - see TbUtilPkg as it moved there
-- 01/2020 2020.01 Updated Licenses to Apache
-- 05/2020 2020.05 Updated LastIndex to also be set during ICover.
-- Updated deallocate to set all variables to their initial value
-- Added GetInc{Index, BinVal, Point}
-- Added GetNext{Index, BinVal, Point}[(Mode => {RANDOM|INCREMENT|MIN})]
-- Added NextPointModeType = (RANDOM, INCREMENT, MIN)
-- Added SetNextPointMode[(Mode => {RANDOM|INCREMENT|MIN})
-- Added to_std_logic(integer), to_boolean(integer) + vector forms
-- RandCov{Point|BinVal} is deprecated, renamed to GetRand{Point|BinVal}
--
--
-- Development Notes:
-- The coverage procedures are named ICover to avoid conflicts with
-- future language changes which may add cover as a keyword
-- Procedure WriteBin writes each CovBin on a separate line, as such
-- it was inappropriate to overload either textio write or to_string
-- In the notes VHDL-2008 notes refers to
-- composites with unconstrained elements
