Ok, ich versuche, eine Block-RAM-Instanziierung im echten Dual-Port-Typ zu erstellen. Ich habe den IP-Katalog und den Blockspeichergenerator in Vivado verwendet, wodurch ich eine riesige Datei erhalten habe, die ich jetzt auf die benötigten Teile reduzieren muss. Dies ist das erste Mal, dass ich internen Block-RAM oder RAM verwende. Meine Frage ist, was ich aus dem ersten Code benötige, damit es in Vivado funktioniert. Der zweite Teil des Codes ist das, womit ich gearbeitet habe und der mir viele Fehler verursacht hat, die ich in einem anderen Thread von Multi-Driver Net gefunden habe.

Das nächste Stück Code, mit dem ich arbeiten sollte. Dieser Teil des Codes gibt mir Fehler, die von mehreren Treibern gefunden wurden. Es wurde auch für einen Spartan-3-Chip geschrieben. Ich brauche einen für einen Artix 7 Chip. Danke

Die Verwendung eines generischen VHDL-Code-Snippets ist viel kleiner....
Beispiel: PoC.mem.ocrom.tdp
entity ocram_tdp is
generic (
A_BITS : positive;
D_BITS : positive
);
port (
clk1 : in std_logic;
clk2 : in std_logic;
ce1 : in std_logic;
ce2 : in std_logic;
we1 : in std_logic;
we2 : in std_logic;
a1 : in unsigned(A_BITS-1 downto 0);
a2 : in unsigned(A_BITS-1 downto 0);
d1 : in std_logic_vector(D_BITS-1 downto 0);
d2 : in std_logic_vector(D_BITS-1 downto 0);
q1 : out std_logic_vector(D_BITS-1 downto 0);
q2 : out std_logic_vector(D_BITS-1 downto 0)
);
end entity;
architecture rtl of ocram_tdp is
constant DEPTH : positive := 2**A_BITS;
signal ram : ram_t;
signal a1_reg : unsigned(A_BITS-1 downto 0);
signal a2_reg : unsigned(A_BITS-1 downto 0);
begin
process (clk1, clk2)
begin -- process

if rising_edge(clk2) then
if ce2 = '1' then
if we2 = '1' then

end if;

end if;
end if;
end process;
q1 <= ram(to_integer(a1_reg)); -- returns new data
