In addition, the functionality of Function Reset is --- validated. --- For each of the objectives above, evaluation of the various generators --- is performed using each of the following techniques. When the states of --- two generators are to be compared, each state is saved, then --- transformed to a bounded-string variable. The bounded-strings can --- then be compared for equality. In this case, matching bounded-strings --- are evidence that the states of two generators are the same. --- In addition, two generators are compared by evaluating a series of --- random numbers they produce. A matching series of random numbers --- implies that the generators were in the same state prior to producing --- the numbers. --- --- --- CHANGE HISTORY: --- 20 Apr 95 SAIC Initial prerelease version. --- 07 Jul 95 SAIC Incorporated reviewer comments/suggestions. --- 22 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1. --- 17 Aug 96 SAIC Deleted Subtest #2. --- 09 Feb 01 RLB Repaired to work on implementations with a 16-bit --- Integer. - ---! - -with Ada.Exceptions; -with Ada.Numerics.Float_Random; -with Ada.Numerics.Discrete_Random; -with Ada.Strings.Bounded; -with ImpDef; -with Report; - -procedure CXA5011 is -begin - - Report.Test ("CXA5011", "Check the effect of Function Reset on the " & - "state of random number generators"); - - Test_Block: - declare - - use Ada.Exceptions; - use Ada.Numerics; - use Ada.Strings.Bounded; - - -- Declare an modular subtype, and use it to instantiate the discrete - -- random number generator generic package. - - type Discrete_Range is mod 2**(Integer'Size-1); - package Discrete_Package is new Discrete_Random(Discrete_Range); - - -- Declaration of random number generator objects. - - Discrete_Generator_1, - Discrete_Generator_2 : Discrete_Package.Generator; - Float_Generator_1, - Float_Generator_2 : Float_Random.Generator; - - -- Declaration of bounded string packages instantiated with the - -- value of Max_Image_Width constant from each random number generator - -- package, and bounded string variables used to hold the image of - -- random number generator states. - - package Discrete_String_Pack is - new Generic_Bounded_Length(Discrete_Package.Max_Image_Width); - - package Float_String_Pack is - new Generic_Bounded_Length(Float_Random.Max_Image_Width); - - use Discrete_String_Pack, Float_String_Pack; - - TC_Seed : Integer; - TC_Max_Loop_Count : constant Natural := 1000; - Allowed_Matches : constant Natural := 2; - -- - -- In a sequence of TC_Max_Loop_Count random numbers that should - -- not match, some may match by chance.
