-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Title : Standard VHDL Synthesis Package (1076.3, NUMERIC_BIT)
--
-- Library : This package shall be compiled into a library symbolically
-- : named IEEE.
--
-- Developers : IEEE DASC Synthesis Working Group, PAR 1076.3
--
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNSIGNED: represents an UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The base element type is type BIT.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array is
-- : returned (exceptions, if any, are noted individually).
--
-- Limitation :
--
-- Note : No declarations or definitions shall be included in,
-- : or excluded from this package. The "package declaration"
-- : defines the types, subtypes and declarations of
-- : NUMERIC_BIT. The NUMERIC_BIT package body shall be
-- : considered the formal definition of the semantics of
-- : this package. Tool developers may choose to implement
-- : the package body in the most efficient manner available
-- : to them.

-- Light8080 simulation test bench.
--------------------------------------------------------------------------------
-- Source for the 8080 program is in asm\@[email protected]
--------------------------------------------------------------------------------
--
-- This test bench provides a simulated CPU system to test programs. This test
-- bench does not do any assertions or checks, all assertions are left to the
-- software.
--
-- The simulated environment has 2KB of RAM, mirror-mapped to all the memory
-- map of the 8080, initialized with the test program object code. See the perl
-- script 'util\hexconv.pl' and BAT files in the asm directory.
--
-- Besides, it provides some means to trigger hardware irq from software,
-- including the specification of the instructions fed to the CPU as interrupt
-- vectors during inta cycles.
--
-- We will simulate 8 possible irq sources. The software can trigger any one of
-- them by writing at registers 0x010 and 0x011. Register 0x010 holds the irq
-- source to be triggered (0 to 7) and register 0x011 holds the number of clock
-- cycles that will elapse from the end of the instruction that writes to the
-- register to the assertion of intr.
--
-- When the interrupt is acknowledged and inta is asserted, the test bench reads
-- the value at register 0x010 as the irq source, and feeds an instruction to
-- the CPU starting from the RAM address 0040h+source*4.
-- That is, address range 0040h-005fh is reserved for the simulated 'interrupt
-- vectors', a total of 4 bytes for each of the 8 sources. This allows the
-- software to easily test different interrupt vectors without any hand
-- assembly. All of this is strictly simulation-only stuff.
--
--
-- Upon completion, the software must write a value to register 0x020. Writing
-- a 0x055 means 'success', writing a 0x0aa means 'failure'. Success and
-- failure conditions are defined by the software.

-- Entity: pwm_check
-- File: pwm_check.vhd
-- Author: Jonas Ekergarn - Aeroflex Gaisler (parts are copied from
-- grtestmod.vhd)
-- Description: Simulation unit that examines the PWMs generated by the GRPWM
-- when software/leon3/grpwm.c is run. Note that pwm_check
-- requires that the system includes an I/O memory interface
-- and that grtestmod.vhd is instantiated in the system testbench.
-- If the subtests in software/leon3/grpwm.c is modified then the
-- configuration below and the procedure verify_subtest must be
-- changed as well.
