Procedure Rules¶
There are three forms a procedure: with parameters, without parameters, and a package declaration:
with parameters
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic) is
begin
end procedure average_samples;
without parameters
procedure average_samples is
begin
end procedure average_samples;
package declaration
procedure average_samples;
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic);
procedure_001¶
This rule checks the indent of the procedure keyword.
Violation
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
Fix
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
procedure_002¶
This rule checks the indent of the begin keyword.
Violation
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
Fix
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
procedure_003¶
This rule checks the indent of the end keyword.
Violation
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
Fix
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
procedure_004¶
This rule checks the indent of parameters.
Violation
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
Fix
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
begin
end procedure average_samples;
procedure_005¶
This rule checks the indent of line between the is and begin keywords
Violation
procedure average_samples (
constant a : in integer;
signal d : out std_logic ) is
variable var_1 : integer;
variable var_1 : integer;
begin
end procedure average_samples;
Fix
procedure average_samples (
constant a : in integer;
signal b : in std_logic;
variable c : in std_logic_vector(3 downto 0);
signal d : out std_logic ) is
variable var_1 : integer;
variable var_1 : integer;
begin
end procedure average_samples;
procedure_006¶
This rule checks the indent of the closing parenthesis if it is on it’s own line.
Violation
procedure average_samples (
constant a : in integer;
signal d : out std_logic
) is
Fix
procedure average_samples (
constant a : in integer;
signal d : out std_logic
) is
procedure_007¶
This rule checks for consistent capitalization of procedure names.
Violation
architecture rtl of entity1 is
procedure average_samples (
constant a : in integer;
signal d : out std_logic
) is
begin
proc1 : process () is
begin
Average_samples();
end process proc1;
end architecture rtl;
Fix
architecture rtl of entity1 is
procedure average_samples (
constant a : in integer;
signal d : out std_logic
) is
begin
proc1 : process () is
begin
average_samples();
end process proc1;
end architecture RTL;
procedure_008¶
This rule checks the end keyword has proper case.
Refer to the section Configuring Uppercase and Lowercase Rules for information on changing the default case.
Violation
END;
End procedure proc;
Fix
end;
end procedure proc;
procedure_009¶
This rule checks the procedure keyword in the end procedure has proper case.
Refer to the section Configuring Uppercase and Lowercase Rules for information on changing the default case.
Violation
end PROCEDURE;
end Procedure proc;
Fix
end procedure;
end procedure proc;
procedure_010¶
This rule checks the identifiers for all declarations are aligned in the procedure declarative part.
Refer to the section Configuring Identifier Alignment Rules for information on changing the configurations.
Violation
variable var1 : natural;
signal sig1 : natural;
constant c_period : time;
Fix
variable var1 : natural;
signal sig1 : natural;
constant c_period : time;
