10 years agoHello.
So, i am change in top level: -- onchip_mem : component hd_mem_onchip_mem -- port map ( -- clk => onchip_mem_clk1_clk, -- clk1.clk -- address => onchip_mem_s1_address, -- s1.address -- clken => onchip_mem_s1_clken, -- .clken -- chipselect => onchip_mem_s1_chipselect, -- .chipselect -- write => onchip_mem_s1_write, -- .write -- readdata => onchip_mem_s1_readdata, -- .readdata -- writedata => onchip_mem_s1_writedata, -- .writedata -- byteenable => onchip_mem_s1_byteenable, -- .byteenable -- reset => onchip_mem_reset1_reset, -- reset1.reset -- reset_req => '1' -- (terminated) -- ); onchip_mem : hd_mem_onchip_mem port map ( clk => clk, address => address, clken => clken, chipselect =>chipselect, write => write, writedata => writedata, byteenable => byteenable, reset => reset, reset_req => reset_req ); And result similar, bus not driving. From outside - i am not driving this signal and me very intresting what need add this is signal to top-level. And about write data - yes i am have array from very slow process, now i am simply write data to register and now for expirience want accum. data to internal ram. If posiible from you are side help - its be nice. In all cases now - this simple project dont write any to on-chip. Me need only one time understand this process. Thank you for understand.
