Warum erhalte ich einen "ungültigen Aggregatfehler" beim Versuch, diesen Datensatz in VHDL zu initialisieren?

Question

Ich möchte einen Datensatz initialisieren. Ich habe online und nach dem Stil von this answer aussehen, aber ich erhalte diese Fehler:

Von Aldec Linter:

Compile Architecture "TB_ARCHITECTURE" of Entity "ten_gig_filter_tb" Error: COMP96_0079: mgmt_regs_rx_TB.vhd : (97, 65): Invalid aggregate. Error: COMP96_0077: mgmt_regs_rx_TB.vhd : (97, 65): Undefined type of expression. Expected type 'tAPB_IBUS_RECORD'.

Von XVHDL Linter:

type of aggregate cannot be determined without context; 0 visible types match here, 32 matches.

Hier ist mein Code:

-- APB BUS - CPU interface 
type tAPB_IBUS_RECORD is record 

    pclk  : std_logic;    --APB Clock, all transactions are synced to this clock 
    presetn  : std_logic;    --APB active low reset. 
    pprot  : std_logic_vector(2 downto 0); --APB protection encoding. 
    pselx  : std_logic;   --slave select pin, when asserted, will activate the slave 
    penable  : std_logic;   -- Enable pin is asserted by the master after the first clock cycle and consecutively until the 
             -- the end of transcation indicated by pready = '1' 
    pwrite  : std_logic;   -- APB Write/Read signal - '1' Write with pselx= '1', '0' - Read along with pselx = '1' 
    pstrb  : std_logic_vector(3 downto 0); -- Write strobe to enable sparse data transfer on the write bus, 0 - byte lane on pwdata(7-0) 
    paddr  : std_logic_vector(19 downto 0); -- 20 bit address bus 
    pwdata  : std_logic_vector(31 downto 0); -- 32 bit data bus 
end record; 

signal iAPB_BUS_IN   : tAPB_IBUS_RECORD := (
          pclk => '0', presetn => '0', pprot => (others => '1'), 
          pselx => '1', pwrite => (others => '0'), penable => '1', 
          pstrb => (others => '1'), paddr => (others => '0'), 
          pwdata => (others => '0') 
          ); 

Answer 1

Es ist, weil dieses Bit falsch ist:

pwrite => (others => '0'), 

Es sollte

pwrite => '0', 

sein, weil pwrite vom Typ std_logic.
